She Helped Test The Vaccine Now She Has Taken It Herself
IOWA CITY For Dr. Patricia Winokur, receiving the vaccine on Monday was in part thanks to her own work. She is a principal investigator on a clinical trial of the Pfizer vaccine, which is the first being rolled out across the United States.
This is the culmination of a lot of hard work, she said while tearing up.
The trial that Dr. Winokur, 61, helped run started in July and ran through October at the University of Iowa Hospitals and Clinics, with 270 volunteers. Some had tested positive for the coronavirus, but others had not they received the vaccine to study the bodys response.
No one in the trial suffered severe reactions, she said, but there were side effects similar to vaccines for the flu, including fatigue, headache and body aches.
One unusual side effect the volunteers reported: pronounced back pain. But most people tolerated the vaccine, and the adverse symptoms went away after a few days, Dr. Winokur said.
Members of the study will receive regular follow-ups for the next two years to determine if they have any lasting adverse reactions, and how long the vaccine remains effective against contracting Covid-19.
I am so proud to have been a part of it, Dr. Winokur said.
Some of them spoke at a news conference about the thinking and procedures that led to them being the first recipients in the city and certainly the highest-profile ones.
Vaccines For Adults Increasing Opportunities For Health
Historically, vaccines were deemed to be only for children. However, vaccines for adults are becoming increasingly common and necessary. Most adults think only of the tetanus booster recommended every 10 years and even then, many adults only get the vaccine if they injure themselves. In 2005, the Tdap vaccine was licensed as an improved version of the typical tetanus booster, Td. The newer version also contains a component to protect against pertussis . All adults, especially those who are going to be around young infants, should get the Tdap vaccine. Adults often unwittingly pass pertussis to young infants for whom the disease can be fatal. In 2012, the CDC recommended that pregnant women get a dose of Tdap during each pregnancy between 27 and 36 weeks gestation. In 2019, the CDC recommended that Tdap or Td vaccine could be used for booster dosing every 10 years.
Influenza vaccines, available since the 1940s, are now recommended for most adults. Vaccines like MMR and chickenpox are recommended for adults who have not had the diseases, and vaccines including hepatitis A, hepatitis B, pneumococcus, and meningococcus are recommended for sub-groups of the adult population. The HPV vaccine became available in 2006. In 2018, the license was expanded to include people up to 45 years of age.
The first formal adult immunization schedule was published in 2002 and is updated annually.
First Authorizations Of Rna Vaccines
In the United States, an Emergency Use Authorization is “a mechanism to facilitate the availability and use of medical countermeasures, including vaccines, during public health emergencies, such as the current COVID19 pandemic.” Once an EUA is issued by the FDA, the vaccine developer is expected to continue the Phase III clinical trial to finalize safety and efficacy data, leading to application for licensure in the United States. In mid-2020, concerns that the FDA might grant a vaccine EUA before full evidence from a Phase III clinical trial was available raised broad concerns about the potential for lowered standards in the face of political pressure. On 8 September 2020, nine leading pharmaceutical companies involved in COVID19 vaccine research signed a letter, pledging that they would submit their vaccines for emergency use authorization only after Phase III trials had demonstrated safety and efficacy.
As of December 2020, many countries and the European Union have authorized or approved the Pfizer-BioNTech COVID19 vaccine. Bahrain and the United Arab Emirates granted emergency marketing authorization for the Sinopharm BIBP vaccine. In the United Kingdom, 138,000 people had received the Pfizer-BioNTech COVID19 vaccine Comirnaty by 16 December, during the first week of the UK vaccination programme. On 18 December 2020, the US FDA granted an EUA for mRNA-1273, the Moderna vaccine. Vaccine manufacturers are awaiting full approvals to name their vaccines.

How Does The Covid
Vaccines prevent diseases that can be dangerous, or even deadly. They work with your bodys natural defenses to safely develop protection from a disease.
A vaccine helps your immune system to produce antibodies, just like it would if you were exposed to the disease. After getting vaccinated, you have protection from that disease, without having to get the disease first.
This is what makes vaccines such powerful medicine. Unlike most medicines, which treat or cure diseases, vaccines prevent them.
Vaccines help our immune system fight infections in the future. The COVID-19 vaccine will protect us from the virus that causes COVID-19 without having to get the illness.
The vaccine will help protect you by teaching your body how to recognize and fight the virus. The vaccine can help keep you from getting COVID-19, but even if you do get the virus, it can keep you from getting very sick.
The COVID-19 vaccine approved for people ages 12-17 years old, from Pfizer/Comirnaty, is given in two doses, about three weeks apart. You need both doses to be fully protected.
It takes a few weeks after the second dose to become fully protected. You may have a sore arm, aches, fatigue, or fever for a few days after getting the vaccine. These symptoms are a sign that your immune system is learning how to protect you from the virus.

States Progress Unevenly In Vaccine Rollout
In the race to vaccinate their residents, Puerto Rico, along with some states with smaller populations in the Northeast, have been leading the way. Some states in the Southeast and Midwest are lagging.
States receive vaccine allocations based on their total adult populations. Each state has its own plan for how to get those vaccines out to its residents through county health offices, hospital systems, pharmacies, mass vaccination sites and mobile clinics. Some states are encountering hesitancy and resistance to getting vaccinated among their populations.
The federal strategy for giving out shots has pivoted from mass vaccination sites, which served millions of people per day at stadiums and conference centers in the spring, to targeted efforts at local pharmacies, doctors’ offices, schools, work sites and community health centers.
The Biden-Harris administration says equity is central to the country’s vaccination efforts. As of November 2, anyone in the U.S. 5 and older is eligible to get a vaccine.
Selena Simmons-Duffin, Ruth Talbot, Thomas Wilburn and Carmel Wroth contributed to this report.
How Is A Vaccine Developed
There are many stages involved in the development and production of a vaccine, from initial academic research to distribution to hospitals and doctors offices.
Clinical trials are crucial indicators of whether a vaccine is effective. Potential vaccines, as with other drugs, are commonly tested in animals first. Human trials are broken up into three phases, progressively increasing the number of volunteers. If a vaccine candidate appears to be ineffective, has harmful side effects, or is too similar to existing vaccines, it wont move on. Trials are often carried out blind, by which some groups are administered the vaccine and some receive a placebo.
If a vaccine candidate is considered successful in human trials, the developers can seek approval by a national or regional regulatory agency, such as the FDA or the European Medicines Agency. In the United States, less than 10 percent of all drugs that go into clinical trials make it past this part of the process. Prior to approval, a vaccine maker can ask the FDA for an emergency use authorization , which allows the sale of unapproved medical products. Finally, the vaccine must be approved by national regulators in other countries to be distributed abroad. Following approval, the vaccine can be manufactured for broad use. In August 2021, the FDA granted approval to the Pfizer-BioNTech vaccine, the first to receive a license in the United States.

Vaccinations In The Us Military
On August 9, 2021, all servicemembers received a memo explaining that, under a plan endorsed by President Biden and by military leadership, COVID-19 vaccination would become mandatory within about a month. About a third of active U.S. military service members had already been vaccinated as of late April and about two-thirds had already been vaccinated by the time the memo was sent.
The U.S. Navy had been the fastest to begin vaccination in early 2021. As of April 22, 2021, considering active military personnel who had received at least one dose, the U.S. Navy had the highest percentage at 51%, the at 36%, the Air Force/Space Force at 34%, and the Army at 27%. By late May, at least 58% of active military personnel had received at least one dose of the COVID-19 vaccine.
As of April 9, 2021, 39% of U.S. Marines to whom the military offered the vaccine had refused it. The highest rate of refusal was at Camp Lejeune in North Carolina, where 57% of Marines had refused the vaccine.
On August 23, 2021, the Pfizer-BioTech vaccine got its full FDA approval, prompting vaccinations to be required for all active duty, reserve, and National Guard troops starting August 25. By the time the vaccination requirement order was sent out, only 68% of active-duty troops were fully vaccinated.
Adaptive Design For The Solidarity Trial
A clinical trial design in progress may be modified as an “adaptive design” if accumulating data in the trial provide early insights about positive or negative efficacy of the treatment. The WHO Solidarity trial of multiple vaccines in clinical studies during 2020, will apply adaptive design to rapidly alter trial parameters across all study sites as results emerge. Candidate vaccines may be added to the Solidarity trial as they become available if priority criteria are met, while vaccine candidates showing poor evidence of safety or efficacy compared to placebo or other vaccines will be dropped from the international trial.
Adaptive designs within ongoing Phase IIIII clinical trials on candidate vaccines may shorten trial durations and use fewer subjects, possibly expediting decisions for early termination or success, avoiding duplication of research efforts, and enhancing coordination of design changes for the Solidarity trial across its international locations.
A Brief History Of Vaccination
The practice of immunisation dates back hundreds of years. Buddhist monks drank snake venom to confer immunity to snake bite and variolation was practiced in 17th century China. Edward Jenner is considered the founder of vaccinology in the West in 1796, after he inoculated a 13 year-old-boy with vaccinia virus , and demonstrated immunity to smallpox. In 1798, the first smallpox vaccine was developed. Over the 18th and 19th centuries, systematic implementation of mass smallpox immunisation culminated in its global eradication in 1979.
Louis Pasteurs experiments spearheaded the development of live attenuated cholera vaccine and inactivated anthrax vaccine in humans . Plague vaccine was also invented in the late 19th Century. Between 1890 and 1950, bacterial vaccine development proliferated, including the Bacillis-Calmette-Guerin vaccination, which is still in use today.
In 1923, Alexander Glenny perfected a method to inactivate tetanus toxin with formaldehyde. The same method was used to develop a vaccine against diphtheria in 1926. Pertussis vaccine development took considerably longer, with a whole cell vaccine first licensed for use in the US in 1948.
Viral tissue culture methods developed from 1950-1985, and led to the advent of the Salk polio vaccine and the Sabin polio vaccine. Mass polio immunisation has now eradicated the disease from many regions around the world
What Are The Leading Covid
Most of the vaccines approved for at least limited use have been developed by firms and research groups in China, Russia, and the United States.
Scores of other COVID-19 vaccine candidates are undergoing large-scale clinical trials and around two hundred potential vaccines are in preclinical development by pharmaceutical companies, academic institutions, and government agencies.

Vaccines Given In Child
Under the FDAs authorization, the Moderna vaccine can be given as a two-dose primary series, with doses given four weeks apart, at 25 micrograms each dose, to infants and children 6 months through 5 years of age.
While the FDA has authorized Modernas vaccine for children ages 6 to 17, the CDC has not yet recommended it for that age group, so those shots cant be administered yet. The FDA authorization would allow children ages 6 to 11 to receive doses are 50 micrograms each. For those ages 12 and older, it would be administered as 100-microgram doses.
The Pfizer/BioNTech vaccine now can be given as a three-dose primary series, at 3 micrograms each dose, for use in infants and children 6 months through 4 years. The vaccine is administered as a two-dose primary series at 10 micrograms per dose for children 5 to 11 and at 30 micrograms per dose for adolescents and adults ages 12 and older.
Completing the Pfizer/BioNTech vaccine series is a longer process, as the first two doses are administered three weeks apart, and then the third dose is given eight weeks later.
Dr. Jeannette Lee of the University of Arkansas for Medical Sciences, who serves on the FDAs vaccine advisory committee, expressed concern about children not completing all three doses.
Is The Vaccine Safe
The COVID-19 vaccine is safe. There are three COVID-19 vaccines available in Massachusetts: Moderna, Pfizer/Comirnaty, and Johnson & Johnson/Janssen. These vaccines were approved or authorized by the Federal Food and Drug Administration only after they were shown to be safe and effective in studies .
Currently, people aged 12-17 can only get the Pfizer/Comirnaty, vaccine.
The U.S. ensures that all vaccines are as safe as possible.
In Massachusetts, a group of infectious disease experts reviewed the safety of the COVID-19 vaccines. This workgroup confirmed that the COVID-19 vaccines authorized by the FDA are safe and effective.
We understand the importance of being open and honest about the safety and development of the vaccine especially for communities who have suffered consequences of medical mistreatment.

In Canada The First Vaccines Leave Health Workers In Tears Of Relief
The start of Canadas vaccine campaign on Monday was an emotional one, with the first precious doses going to people from nursing homes: health care workers in Toronto, and residents in both Montreal and Quebec City.
That was recognition that nursing homes have been ground zero in Canada when it comes to both Covid-19s cruel ravages and the storm of criticism over the countrys lack of preparation for it. More than 460,000 people have tested positive for the coronavirus in Canada, and 13,400 have died from it.
We have never distributed so many Kleenex boxes as the last few days, said Sue Graham-Nutter, chief executive officer of the Rekai Centres, which runs two nursing homes in Toronto tapped to receive the countrys first vaccinations. We have the images of what happened on the floors.
Less than a week after Canada became the third country in the world to approve the vaccine created by the American drugmaker Pfizer and a German firm, BioNTech, the first shipment arrived to a Montreal airport on Sunday night. From there, kicking off the countrys largest largest-ever inoculation program, the boxes of frozen vials were dispersed to 14 sites across most of the country that were equipped with special freezers for the vaccine, which needs to be kept at ultracold temperatures.
How Does The Vaccine Work
The Pfizer/BioNTech vaccine was the first coronavirus jab to show promising results in the latter stages of its testing process.
It is a new type called an mRNA vaccine that uses a tiny fragment of genetic code from the pandemic virus to teach the body how to fight Covid-19 and build immunity.
“The vaccine contains a small piece of the virus’s mRNA that instructs cells in the body to make the virus’s distinctive ‘spike’ protein,” the FDA said.
“When a person receives this vaccine, their body produces copies of the spike protein, which does not cause disease, but triggers the immune system to learn to react defensively, producing an immune response against .”
The vaccine is given as two injections, 21 days apart, with the second dose being a booster. Immunity begins to kick in after the first dose but reaches its full effect seven days after the second dose.
The vaccine must be stored at ultra-low temperatures, which makes distribution difficult. Special shipping containers that use dry ice will be used to transport frozen vials direct to the point of vaccination, Pfizer says.
The pharmaceutical company has agreed a deal to supply the US with 100 million doses of the vaccine by March.
An additional 200 million doses of a second vaccine, developed by Moderna and the National Institutes of Health, will be provided by June. However this vaccine is still seeking approval in the US.
