Monitoring Safety Of Hpv Vaccines

HPV vaccination for teenagers

The Yellow Card Scheme allows doctors, other healthcare professionals and members of the public to report suspected side effects from any medicine taken, including vaccines.

It’s run by the Medicines and Healthcare products Regulatory Agency .

The scheme regularly reviews the reports and, if there’s a potential problem, will carry out an investigation and take appropriate action if necessary.

There’s also a legal requirement for pharmaceutical companies to report serious and suspected adverse events to the MHRA.

Are Hpv Vaccines Safe

Yes. More than 12 years of safety monitoring show that the vaccines have caused no serious side effects. The most common problems have been brief soreness and other local symptoms at the injection site. These problems are similar to those commonly experienced with other vaccines.

The FDA and the CDC conducted a safety review of adverse side effect s related to Gardasil immunization that have been reported to the Vaccine Adverse Events Reporting System since the vaccine was licensed . The rates of adverse side effects were consistent with what was seen in safety studies carried out before the vaccine was approved and were similar to those seen with other vaccines. The most recent safety data review for HPV vaccines continues to indicate that these vaccines are safe .

Syncope is sometimes observed with Gardasil, as with other vaccines. Falls after fainting may sometimes cause serious injuries, such as head injuries. These can largely be prevented by keeping the person seated for up to 15 minutes after vaccination. The FDA and CDC have reminded health care providers that, to prevent falls and injuries, all vaccine recipients should remain seated or lying down and be closely observed for 15 minutes after vaccination. More information is available from the CDC on its Human Papillomavirus Vaccine page.

Information From Fda And Cdc On The Safety Of Gardasil Vaccine

Consumers, parents, health care professionals and others have raised questions regarding the safety of the human papillomavirus vaccine, Gardasil. FDA and the U.S. Centers for Disease Control and Prevention take all concerns about vaccine safety seriously, and have been closely monitoring the safety of Gardasil.

Below is a summary of Gardasil vaccine safety monitoring activities and findings. Based on ongoing assessments of vaccine safety information, FDA and CDC continue to find that Gardasil is a safe and effective vaccine. FDA and CDC continue to monitor the safety of this vaccine, with the publics health and safety our top priority.

Gardasil Background

FDA approved Gardasil on June 8, 2006. It is approved for females 9-26 years of age to protect against cervical, vulvar and vaginal cancers caused by Human Papillomavirus types 16 and 18 and genital warts caused by HPV types 6 and 11. CDC’s Advisory Committee on Immunization Practices recommended a routine 3-dose vaccination series for girls 11 and 12 years of age. The vaccine is also recommended for girls and women ages 13 through 26 years who have not yet been vaccinated or who have not received all 3 doses.

Adverse Event Reports following Gardasil


Based on the review of available information by FDA and CDC, Gardasil continues to be safe and effective, and its benefits continue to outweigh its risks.

Who Should Get Hpv Vaccine


HPV vaccination is recommended for all preteens at age 1112 years. All preteens need HPV vaccination, so they are protected from HPV infections that can cause cancer later in life.

  • Teens and young adults through age 26 years who didnt start or finish the HPV vaccine series also need HPV vaccination.

CDC recommends that 11- to 12-year-olds receive two doses of HPV vaccine 6 to 12 months apart.

  • The first dose is routinely recommended at age 1112 years old the series can be started at age 9 years.
  • Only two doses are recommended if vaccination started at age 9 and through age 14.

Teens and young adults who start the series later, at ages 15 through 26 years, need three doses of HPV vaccine.

  • Adolescents aged 9 through 14 years who have already received two doses of HPV vaccine less than 5 months apart will require a third dose.
  • Three doses are recommended for people with weakened immune systems aged 9 through 26 years.

Vaccination is not recommended for everyone older than age 26 years. However, some adults age 27 through 45 years who are not already vaccinated may decide to get HPV vaccine after speaking with their doctor about their risk for new HPV infections and the possible benefits of vaccination. HPV vaccination in this age range provides less benefit, as more people have already been exposed to HPV.

These tests are usually used to identify women who are at high-risk of having precancerous changes and developing cervical cancer. Research shows that HPV testing is more accurate than the Pap test in finding precancerous changes in the cervix. Researchers are still trying to find the best way to use the HPV test as a part of cervical cancer screening. are an effective way to find cervical cancer.

HPV tests are available in some areas of Canada. In provinces that use HPV tests as part of their cervical cancer screening programs, they are generally used as a follow-up to abnormal Pap tests results.

What Is In The Vaccine

The HPV vaccine used in the New Zealand Immunisation Programme from 2017 is Gardasil® 9. The vaccine contains HPV virus-like particles of HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58. These particles are proteins from the outer shell of the virus. The VLPs do not contain DNA fragments in a form that could allow them to infect cells or reproduce. The particles mimic the HPV virus so that the immune system makes antibodies against it. These recombinant types of vaccine have been used around the world for over 20 years.

Each 0.5ml dose of the vaccine also contains a small amount of aluminium, which stimulates the immune response. Aluminium has been safely and effectively used in vaccines for more than 70 years. The vaccine also contains tiny amounts of sodium chloride , L-histidine , Polysorbate 80, sodium borate and sterile water.

The vaccine does not contain preservatives, antibiotics or any human or animal materials.

So Why Is There No Vaccine For Hiv Cancer Or The Common Cold

Human immunodeficiency virus, the culprit behind acquired immunodeficiency syndrome, commonly known as AIDS, is a tricky virus. Much like the novel coronavirus, HIV binds to a protein on the surface of T cells, a type of white blood cell, to enter. Once inside, HIV integrates its genetic material with its host cell’s DNA, using the host’s DNA replication machinery to create new viruses, which blast off to infect and kill other T cells.

Finding a specific and effective vaccine target is therefore difficult, especially since HIV mutates frequently in order to mask itself from the immune system. According to the National Institute of Allergy and Infectious Disease, common vaccine approaches using inactivated or live HIV forms have either not been “effective in eliciting immune responses in clinical trials” or are too dangerous to use.

The same goes for the common cold, which is caused by a smorgasbord of viruses including over 150 different types of rhinovirus, a common troublemaker.

“It’s hard to create a vaccine when you have so many different viruses causing similar symptoms. To make a universal vaccine against all of them is probably pretty daunting, it might be doable, but it’s daunting,” explained Hotez.

Vaccines For Adolescents: A New Generation Of Vaccines

Can the HPV Vaccine Cause Infertility? â Answers from a Pediatrician

Adolescents, like adults, were recommended to get tetanus boosters every 10 years most requiring their first booster dose around age 11. Other than this, however, most adolescents did not require additional vaccines unless they missed one in childhood. By 2005, vaccines specifically recommended for adolescents were only recommended for sub-groups based on where they lived or medical conditions that they had. However, a new group of vaccines became available in the latter part of the decade.

  • New vaccines: Tdap, 2005, meningococcal conjugate , HPV , meningococcal serogroup B vaccine
  • Additional recommendations for existing vaccines: HPV , intranasal influenza vaccine
  • New versions of existing vaccines: HPV
  • Discontinuation of vaccine: intranasal influenza vaccine

False Claims About Autism

In 1998 Andrew Wakefieldet al. about twelve children, reportedly with bowel symptoms and autism or other disorders acquired soon after administration of MMR vaccine, while supporting a competing vaccine. In 2010, Wakefield’s research was found by the General Medical Council to have been “dishonest”, and The Lancet fully retracted the paper. Three months following The Lancet’s retraction, Wakefield was struck off the UK medical register, with a statement identifying deliberate falsification in the research published in The Lancet, and was barred from practising medicine in the UK. The research was declared fraudulent in 2011 by the British Medical Journal.

Since Wakefield’s publication, multiple peer-reviewed studies have failed to show any association between the vaccine and autism. The Centers for Disease Control and Prevention, the Institute of Medicine of the National Academy of Sciences, the UK National Health Service and the Cochrane Library review have all concluded that there is no evidence of a link.

In Japan, the MMR triplet is not used. Immunity is achieved by a combination vaccine for measles and rubella, followed up later with a mumps only vaccine. This has had no effect on autism rates in the country, further disproving the MMR autism hypothesis.

The component viral strains of MMR vaccine were developed by propagation in animal and human cells as all viruses require a living host cell to replicate.

Hpv Vaccination For Men Who Have Sex With Men

Men who have sex with men have not benefited in the same way from the longstanding girls’ programme, so may be left unprotected against HPV.

Since April 2018, MSM up to and including 45 years of age have been eligible for free HPV vaccination on the NHS when they visit sexual health clinics and HIV clinics in England.

Ask the doctor or nurse at the clinic for more details.

Hpv Vaccination Is Very Safe

Each HPV vaccine 9-valent HPV vaccine , quadrivalent HPV vaccine , and bivalent HPV vaccine went through strict safety testing before the U.S. Food and Drug Administration licensed them. Over 15 years of monitoring and research during the vaccination program have continued to show that HPV vaccination is safe.

Gardasil® 9 was studied in clinical trials with more than 15,000 females and males.

Gardasil® was studied in clinical trials with more than 29,000 females and males.

Cervarix® was studied in clinical trials with more than 30,000 females.

Each vaccine was found to be safe and effective in clinical trials. Since late 2016, Gardasil® 9 has been the only HPV vaccine available for use in the United States.

As with all approved vaccines, CDC and FDA closely monitor the safety of HPV vaccines. Any detected safety concerns are reported to health officials, healthcare professionals, and the public.

More than 135 million doses of HPV vaccines have been distributed since they were licensed. Data continue to show the vaccines are safe and effective.

Vaccine Development In The 1980s Hepatitis B And Haemophilus Influenzae Type B

The vaccine for Haemophilus influenzae type b was licensed in 1985 and placed on the recommended schedule in 1989. When the schedule was published again in 1994, the hepatitis B vaccine had been added.

The hepatitis B vaccine was not new, as it had been licensed in 1981 and recommended for high-risk groups such as infants whose mothers were hepatitis B surface antigen positive, healthcare workers, intravenous drug users, homosexual men and people with multiple sexual partners. However, immunization of these groups didn’t effectively stop transmission of hepatitis B virus. Thats because about one-third of patients with acute disease were not in identifiable risk groups. The change of recommendation to immunize all infants in 1991 was the result of these failed attempts to control hepatitis B by only immunizing high-risk groups. Following this recommendation, hepatitis B disease was virtually eliminated in children less than 18 years of age in the United States.

Hpv Vaccination Is Preventing Cancer

HPV infections and cervical precancers have dropped since 2006, when HPV vaccines were first used in the United States.

  • Among teen girls, infections with HPV types that cause most HPV cancers and genital warts have dropped 88 percent.
  • Among young adult women, infections with HPV types that cause most HPV cancers and genital warts have dropped 81 percent.
  • Among vaccinated women, the percentage of cervical precancers caused by the HPV types most often linked to cervical cancer has dropped by 40 percent.

Testing And Licensing Of Sabin Polio Vaccine

For four years, researcher Albert Sabin partnered with health officials from the Soviet Union to produce a more affordable alternative. More than 10 million children received his oral polio vaccine during this period.

Studies showed that Sabins version triggered a faster immune response and was easier to administer than Salks vaccine. Both Salks injectable vaccine and Sabins oral vaccine stopped the spread of all strains of the poliovirus through the bloodstream.

Ultimately, the U.S. Surgeon General recommended licensing of Sabins OPV, which combined vaccinations against all three types of polio in 1963.

In the decades that followed, widespread use of the polio vaccine finally began to stem the tide of this contagious disease. The World Health Organization would later launch a global poliovirus eradication program in the 80s.

Scientists in New York City grew the poliovirus in embryonic brain tissue, allowing them to study how the virus spread. However, they were reluctant to create a vaccine in this manner due to the risks associated with using nervous system tissues. This particular study did at least advance the medical communitys understanding of the poliovirus ability to multiply.

Hpv Vaccine Cutting Cervical Cancer By Nearly 90%

The human papillomavirus, or HPV, vaccine is cutting cases of cervical cancer by nearly 90%, the first real-world data shows.

Cancer Research UK described the findings as “historic”, and said it showed the vaccine was saving lives.

Nearly all cervical cancers are caused by viruses, and the hope is vaccination could almost eliminate the disease.

The researchers said the success meant those who were vaccinated may need far fewer cervical smear tests too.

Cervical cancer is the fourth most common cancer in women around the world, killing more than 300,000 each year.

Almost nine-in-10 deaths are in low and middle income countries where there is little access to cervical cancer screening. The hope is vaccination will have an even bigger impact in those countries than wealthier nations such as the UK.

More than 100 countries have starting using the vaccine as part of World Health Organization plans to get close to eliminating cervical cancer..

In the UK, girls are offered the vaccine between the ages of 11 and 13, depending on where they live. The vaccine has also been offered to boys since 2019.

The HPV vaccine can only prevent an infection, it cannot rid the body of the virus once it has been caught. The viruses are so widespread that immunisation has to be aimed at children before they become sexually active.

“The impact has been huge,” said Prof Peter Sasieni, one of the researchers at King’s College London.
