Everyone 12 years old and up are now eligible to receive free COVID booster shots. All brands are approved, and whichever type of vaccine you want to get is the best kind for you, so mix and match your boosters.
All individuals 6 months and over are now eligible to receive Pfizer vaccines
Boosters are now available at the CNCHD clinic, but COVID vaccine appointments are not available, so plan at least an hour for your visit.
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.
The Pfizer booster is for ages 12 and up. The Moderna booster is for 18 and up. Novavax can receive a Pfizer or Moderna bivalent booster at 12 years and up after the primary doses. Boosters can be administered no sooner than two months since your last dose.
YES, your booster 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 booster sooner than six months is harmful, it’s unnecessary. These timelines are based on extensive research indicating that these are sweet spots 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 initial vaccine roll outs.
No sweat. Just come in when you can.
At that time, data wasn’t clear on when boosters 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.
Individuals who received Pfizer are eligible for a booster at 12 years old and up. Those who received Moderna are eligible for a booster at 18 years old and up. Your booster should DOES NOT need to be the same brand as your initial doses, so you may “mix and match.” For example, if you received an initial Pfizer vaccine, you may receive Moderna for your booster. This is totally up to you and your primary care provider.
Yes. Mix and match as you see fit. Talk to you primary care provider for more information on the best choice for you.
No. The bivalent booster vaccine is different than the original vaccine. It covers original COVID-19 and Omicron BA.4/BA.5
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 dose(s) 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.
