How Many Different Vaccines Are There

Vaccines For Adults Increasing Opportunities For Health

How many Covid vaccines have been approved and when will they be ready? | ITV News

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.

How Do Mandatory Vaccination Policies Vary By Region

We found that assessing policies across WHO regions European, Americas, Western Pacific, African, and Eastern Mediterranean was a useful way to break down our analysis of policies worldwide.

In the chart you see a breakdown of the number of countries with a given policy mandate. You can view this by region by using the Change region toggle on the interactive chart.

Europe has a mixture of mandatory and recommended policies. But most European countries 16 out of 28 do not have mandatory vaccination. European countries were among the first to introduce mandatory vaccination for smallpox in the early 19th century, which also led to early push-back. The early introduction and early push-back, along with present-day approaches to foster mutual trust and responsibility between citizens and the health authorities, may be part of the reason why vaccination is often recommended rather than mandated in many European countries.50 Countries of the former-USSR or under the influence of the Eastern Bloc previously had mandatory vaccination, and many kept this policy in the post-USSR era.

Most countries in the Americas 29 out of 35 have mandatory vaccinations. In the USA, vaccination is regulated by individual states though it is mandatory for school entry in all of them. In Canada, only three provinces have legislated mandatory vaccination policies that apply to children enrolling in school.

All booster shots will be free, regardless of immigration or health insurance status. However, depending on where you get your booster shot — for example, at a local pharmacy — you may be asked to provide your insurance card information, including your name, date of birth and membership number. But ou will not be charged for your COVID-19 vaccine or booster shot.

Are They Suitable For People Who Are Immunocompromised

Although vaccines are usually safe for people who are immunocompromised, people who are severely so are sometimes advised to avoid live vaccines, because even the weakened virus can make them very sick. Encouragingly, early studies suggest that all four of the vaccine technologies currently being used are suitable for people who are immunocompromised, and as none of these technologies use ‘live’ virus, they should not pose a problem in this respect.

Researchers have been interested in DNA and mRNA-based vaccines for many years. Over the past several years, researchers have worked on many different mRNA-based vaccines for infectious diseases like HIV,rabies, Zika, and influenza.

However, none of these other vaccines have reached the stage of development leading to official approval by the FDA for use in humans. The same is true of DNA-based vaccines, although some of these have been approved for veterinary uses.

Both the Pfizer and Moderna COVID-19 vaccines are mRNA-based vaccines. Several other DNA and mRNA-based vaccines are currently undergoing clinical trials around the world.

Why Are The Pfizer And Moderna Vaccines Preferred For People Aged 59 And Under

There is a link between the AstraZeneca vaccine and a very rare condition called thrombosis with thrombocytopenia syndrome . The risk of this occurring is slightly higher in younger adults than in older adults. TTS typically occurs around 4 to 42 days after AstraZeneca vaccination and can be treated very effectively.

Therefore, the Australian Technical Advisory Group on Immunisation recommends that the Pfizer and Moderna vaccines are the preferred vaccines for people aged 59 and under.

However, if youre aged 18 to 59 years, you can have the AstraZeneca vaccine if youve weighed up the benefits and the risks, and you provide informed consent.

What Is The Omicron Variant

The new variant was first detected in specimens collected on November 11, 2021 in Botswana. Experts in South Africa first reported the Omicron variant to the World Health Organization on Nov. 24, 2021. They discovered the variant after COVID-19 infections suddenly began to go up.

The WHO grouped Omicron as a Variant of Concern. This category means the variant might have a higher transmissibility, cause more intense disease, and may be less likely to respond to vaccines or treatments. But researchers need more information to confirm these factors.

Early evidence suggests that the Omicron variant causes a higher risk of reinfection compared to other variants.

Current PCR tests for COVID-19 can effectively find Omicron cases. Experts found that one specific PCR test doesn’t identify one of the three target genes in people infected with Omicron. Because of this, these tests can specifically mark positive Omicron cases and, because of that, can detect this variant faster than with previous surges.

According to research, breakthrough infections are possible with the Omicron variant even if youre fully vaccinated. However, COVID-19 vaccines and boosters are still effective at preventing severe illness, hospitalizations, and death.

The Omicron variant is now the dominant strain in the U.S.

Experts are keeping a close eye on how the variant spreads or develops.

What Is A Vaccine

Vaccination prepares the immune system to fight against a future infection. Vaccines often contain tiny amounts of dead or weakened viruses or bacteria, called antigens. The immune system responds to these antigens without you getting sick, effectively training the immune system to fight the disease if exposed to it in the future.

Some vaccines need to be given more than once known as booster vaccinations. Some vaccines, such as the seasonal influenza vaccine, only work for a short period of time. This is because the virus itself can change over time.

Vaccines are usually given with an injection.

The Schedule From 2011 To Present

There are four types of COVID-19 vaccines: heres how they work

Annual updates to both the childhood and adult immunization schedules offer guidance to healthcare providers in the form of new recommendations, changes to existing recommendations, or clarifications to assist with interpretation of the schedule in certain circumstances. The schedules are reviewed by committees of experts from the Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the American Academy of Family Physicians.

Important changes to the schedule:

  • New vaccines: meningococcal serogroup B vaccine
  • Additional recommendations for existing vaccines: HPV , intranasal influenza vaccine
  • Discontinuation of vaccine: intranasal influenza vaccine

How Have The Covid

The urgency of the pandemic has meant that all available resources and efforts have been directed towards finding effective vaccines.

Globally, some COVID-19 vaccines were approved and administered just 12 months after the virus was discovered. Usually, development of a vaccine takes several years. Some of the reasons behind this rapid progress include:

  • The levels of funding and collaboration between vaccine developers and governments are greater than ever before. Planning began early, including investment in manufacturing facilities before a vaccine was even available.
  • Technology makes vaccine development faster than in the past. To develop a vaccine, scientists need to understand the viruss genetic code. New technology allowed researchers to quickly identify the genetic code of the COVID-19 virus soon after it emerged. This allowed scientists around the world to start designing and building vaccines.
  • Clinical trials progress more quickly if a disease is widespread, which is the case for COVID-19 in many countries. This means researchers can evaluate the effect of a vaccine on both unvaccinated and vaccinated groups much sooner than theyd be able with a rare disease.

Will Children Be Given A Coronavirus Vaccine

This is the subject of quite intense debate, although the UK regulator has approved the use of the Pfizer vaccine in adolescents aged 12-15 and some countries, including the US, have begun administering vaccines to this age group. The regulator is currently reviewing evidence on the need to vaccinate younger children here.

In the UK, COVID-19 is thought to be spreading faster in children than in adults, but thats not necessarily a reason to give them doses. If children are not generally vulnerable to the virus, then its argued that doses are put to better use in the arms of vulnerable adults in other countries. Beyond the ethics of such a decision, this might also lower the risk of new, vaccine-proof variants emerging around the world.

However, if children are spending a lot of time with vulnerable adults in, for example, multi-generational households, then vaccinating them could offer their vulnerable relatives an extra layer of protection.

Can The Moderna Booster Protect Against Omicron

So far, so good.

According to research by Imperial College London, booster vaccines are 80% effective against the Omicron variant. However, this study was conducted specifically with Pfizer boosters. Imperial scientists also say that Omicron variant-specific vaccines are likely to be required to stop infections.

Today Moderna released some specific data about how well their vaccine works.

According to the stats, a booster dose of 50 micrograms increases protection 37 times above the level of antibodies that were there with a double-dose. On the other hand, a 100 microgram dose pushes that protection up 83 times what it already was. Right now, this data still needs to be peer-reviewed, but it remains quite hopeful.

For reference, both initial shots of Moderna are 100 micrograms each.

The company are working on a vaccine that targets Omicron, with clinical trials set to begin in early 2022. For now, only real-world data can explain if the vaccine can protect people throughout the winter.

The dramatic increase in COVID-19 cases from the Omicron variant is concerning to all. said Stéphane Bancel, Moderna CEO.

Efficacy:72.8%Along with their Beijing Institute vaccine, Sinopharm also tested an inactivated virus vaccine developed by the Wuhan Institute of Biological Products. The Phase 1/2 trial showed that the vaccine produced antibodies in volunteers, some of whom experienced fevers and other side effects. Sinopharm then launched a global Phase 3 trial of the Wuhan vaccine. In December, Peru briefly paused their trial to investigate neurological problems that one volunteer experienced, but determined that it had nothing to do with the vaccines. On Feb. 25, China announced the approval of the Wuhan vaccine for general use. In May, the vaccine researchers the results of the Phase 3 trial, demonstrating that the vaccine has an efficacy of 72.8 percent.Approved for use in:China.Limited use in: United Arab Emirates.Updated May 29

Should People Who Are Pregnant Get A Booster Shot

The COVID-19 booster recommendations apply to all people 18 years and older, including those who are pregnant. The CDC urges pregnant people to get a COVID-19 vaccine, a booster is half a full vaccine dose.

“People who are pregnant or recently pregnant are more likely to get severely ill with COVID-19 compared with people who are not pregnant,” the CDC says on its website.

While there is no evidence that getting vaccinated decreases fertility in women or men, a recent study also linked COVID-19 infection in pregnant people to a higher risk of stillbirth.

Eradication Of Diseases Through Vaccination

Eradication is the ultimate goal of vaccination against a disease.

On the way to the eradication of polio

Polio is targeted for global eradication. This has become possible through the polio vaccine that was developed in 1955. The WHO estimates that in 2015, 85% of infants around the world received three doses of polio vaccine. And the number of paralytic polio cases have since the 1980s, from an estimated 350,000 to 400,000 paralytic cases per year to 22 reported cases in 2017.

Eradication of smallpox

While the benefits might possibly be forgotten as vaccine-preventable diseases have lost their threat thanks to the introduction of the vaccines it is still true that people around the world including those in richer countries continue to benefit from vaccinations.

One of the greatest successes of global health is eradication of smallpox. Smallpox, which just decades ago killed several hundred thousand people every year was successfully eradicated in 1980 thanks to the global vaccination program.21

What Does The Moderna Booster Shot Do

As the vaccine’s effectiveness decreases over time, a COVID-19 booster shot — whether from Moderna, Pfizer or Johnson & Johnson — recharges your body’s immune response and guards against a breakthrough infection.

Recent studies of the Pfizer and AstraZeneca vaccines show that their effectiveness can begin to wane after six months. Moderna said early data suggests that those who received the Moderna vaccine in 2020 are showing a higher rate of breakthrough COVID-19 infections than those vaccinated this year, suggesting the need for a booster to maintain high levels of protection.

Are There Any Side Effects From The Vaccines

Oxford-AstraZeneca: There are no dangerous side effects to the AstraZeneca jab. However, people may experience fatigue, a fever or a headache that can be managed with paracetamol, according to researchers.

Currently there is on-going research into blood clots following the vaccine, however, there is yet enough evidence to support this claim.

Pfizer-BioNTech: Adverse reactions are similar to the Oxford drug but may also include enlarged lymph nodes or temporary one-sided facial drooping . It is unknown how frequently people have severe allergic reactions to the vaccine.

Moderna: Mild to moderate adverse reactions usually resolve themselves in a matter of days, while pain at the injection site, fatigue, headaches and muscle pain are the most common side effects of Moderna’s vaccine. Swelling of the face is rare, whereas severe allergic reactions and hypersensitivity have an unknown frequency.

Research has shown people mostly display similar mild or moderate side effects from the Novavax vaccine as seen in those above. A small percentage of volunteers in trials experienced severe adverse reactions but none needed to be hospitalised.

The company said side effects to the Janssen vaccine included headaches, bodily aches and, more rarely, fever. However, more studies are ongoing into adverse reactions.
