Most patients do not experience anything other than a mildly sore arm after the first dose. The second dose appears to really stimulate your immune system, which is a good thing, that’s the whole point of the vaccine. It is common to feel like you are coming down with a cold/flu the day after your second shot. You may have a headache, fever, body aches and fatigue… it tends to only last about a day. It is very important to understand that this is expected. What you are feeling is your immune system building a strong defense against COVID.

BEFORE THE SECOND SHOT, we do not recommend taking prescription or over-the-counter pain medications, as this could blunt the immune response. AFTER THE SECOND SHOT, tough it out if you can. If needed, consider taking over-the-counter pain medications, such as Tylenol, acetaminophen, Motrin, ibuprofen.

Yes, the vaccine is highly effective and your body is building a response to the vaccine even if you don’t have any side effects.

Seek medical attention if you experience any respiratory problems such as trouble breathing or if the symptoms persist after two days.

The Pfizer vaccine reaches its full effect one to two weeks after the second dose.

Antibody testing to see if the vaccine worked is not recommended.

Research is ongoing, but a preliminary study shows that the Pfizer vaccine is effective against at least two of the new variants studied.

More time is needed to study how long immunity lasts. Studies show that people who were vaccinated had a very strong immunity to COVID-19 but scientists don’t yet know how long that immunity will last.

We do not know if people can still spread the virus after getting vaccinated or the impact of the variant strains. Please continue to wear masks and practice social distancing. Here is a link to the latest advice from the CDC.

Absolutely. Keep your proof of vaccination in a safe place. It may be required for future travel or return to work or school.
