HPV Vaccine Effectiveness for Individuals Already Infected?
The Human Papillomavirus (HPV) vaccine is a crucial tool in the fight against one of the most common sexually transmitted infections (STIs) in the United States. This vaccine, available as Gardasil 9 since 2016, protects against nine of the highest-risk strains of HPV, some of which can lead to cancer.
HPV is the most common STI in the country, with cases reported in 2018. Each year, approximately 35,000 cancers in the United States are caused by HPV. The CDC advises that males, as well as females, receive the HPV vaccine to reduce the risk of developing these cancers and other HPV-related diseases.
The HPV vaccine is typically administered during childhood before exposure to HPV. However, it is also available for individuals up to 45 years old. The Centers for Disease Control and Prevention (CDC) recommend HPV vaccination for adults aged 27 through 45 years who are at risk for new HPV infection and might benefit from vaccination. This group includes those who may have been exposed to HPV and could still gain protection despite being older than 26 years.
The side effects of the HPV vaccine are mild and include soreness, swelling, nausea, headache, fever, fatigue, dizziness, and fainting. To prevent falls and potential injuries due to fainting, the CDC advises healthcare professionals to have anyone receiving the HPV vaccine remain sitting or lying down under observation for a while after the vaccination.
It's worth noting that anyone with HPV, regardless of age, should still receive the vaccine if they are not already vaccinated. Additionally, the HPV vaccine helps protect people against external genital warts. For individuals aged 9-26 years old who already have HPV, the vaccine may still offer protection against other strains of HPV that they do not have.
The CDC also recommends the HPV vaccine for anyone aged 13-26 years who have not received it or who have only received a partial dose. Anyone wishing to receive an HPV vaccination after the age of 26 years, or anyone who already has HPV, should speak with their doctor about their suitability.
In conclusion, the HPV vaccine is a vital tool in the prevention of HPV-related cancers and other diseases. It is recommended for individuals up to 45 years old, and its benefits extend to those who have already been exposed to HPV, as it can provide protection against other strains of the virus. As always, it's essential to consult with a healthcare professional to determine the best course of action.
