your COVID-19 vaccine, you may feel some slight side effects, just like you

annual vaccine or just the initial vaccine, it is important that we all do our part to
stop COVID-19 from taking over our lives, our jobs, and our communities.
4. What should parents know about the vaccines for those younger than 16
years of age?
If we want to protect all of our loved ones from this deadly virus, we all need to
be vaccinated. The COVID-19 vaccines, like other vaccines your children get, are
safe and effective and help us eradicate disease in our community. Remember
that only the Pfizer vaccine is available for those who are 12-17 years old.
