Third Dose FAQs

Vaccines are highly effective in preventing COVID hospitalization and death, even against the Delta variant. However, when any virus is so pervasive in society like COVID is now and has countless opportunities to infect hosts, the vaccine that is fighting the virus can weaken over time. The FDA, CDC and other health agencies have been monitoring data since vaccines were first administered in December 2020, and we’ve learned that protection against mild and moderate COVID is decreasing over time – even though protection against the worst COVID outcomes remain high. We are concerned that this pattern of decline will continue and eventually lead to less protection against severe illness, so that’s why we need third doses. It’s an additional layer of protection.

Right now, anyone who has received their second dose of Pfizer six months prior AND meet one of the following criteria: 65 and over, living in long-term care facility, OR 50-64 with underlying conditions.

You are eligible for a third dose 6 months after your second dose of Pfizer vaccine.

YES, your third dose is free to you. Please bring your insurance card if you have one.

Please bring your vaccine card, ID and insurance card if you have one. If you’ve lost your vaccine card, we can look yours up and provide you with a new one. Oh, and a smile.

Although there’s no evidence to indicate getting your third dose sooner than eight months after your second one is harmful, it’s unnecessary. This timeline is based on extensive research indicating that the 6 month mark is a sweet spot for boosting immunity and providing optimal protection. Additionally, this system prioritizes protecting our community’s most vulnerable and exposed populations, just as we did in the initial vaccine roll out.

No sweat. Just come in when you can.

At that time, data wasn’t clear on when a third dose would be necessary, but additional doses were expected. Flu shots require annual boosters both because the virus mutates and because our immunity wanes, which is exactly what’s happening with COVID.

Pfizer is eligible for third doses. The CDC is still studying data to determine if/when Moderna and Johnson & Johnson will require an additional dose.

Yes. The third dose is the exact same medication, ingredients and dosage amounts as the first two doses.
Yes. Side effects are mild and could include arm soreness or other flu like symptoms for around 24 hours.
Vaccines remain the single most effective tool in the fight against Covid. Your initial doses will provide you protection against the most severe illness, but data is indicating that protection does wane over time. That being said, any vaccine protection is better than none.
