What’s in the bivalent booster?

According to Dr. Ostrosky, the bivalent booster was crafted like your typical flu shot. The vaccine contains proteins from the initial COVID-19 strain along with subvariant strains to better protect individuals in one single shot. The new dose is also referred to as the omicron booster. 

When should you get the booster?

If you can get the booster now, you should. Dr. Ostrosky says that with the winter season approaching, now is an optimal time to protect yourself against all strains of COVID-19. If you’ve had COVID-19 in the past three months, received another vaccine, or haven’t received any vaccine at all, you should speak to a healthcare provider before receiving the bivalent booster. 

Who can receive the booster?

The CDC allocated a total of 900,000 doses of the bivalent boosters in Texas. Of those, there are 502,500 doses of Pfizer’s booster and 192,800 of Moderna’s. The Pfizer booster is available for people ages 12 and up, and Moderna has been approved for those 18 and up. 

Can you receive a bivalent booster and a flu shot?

Dr. Ostrosky says that both vaccines can be administered in tandem. “To save yourself time, you can receive your COVID and flu shot at the same time. Over the past two years, we’ve learned it’s perfectly safe to receive both together. We’re getting to the place where people will start receiving these two shots every September or October.”

What are the side effects of the booster?

Much like the original COVID-19 vaccine, those who receive the bivalent booster will experience similar symptoms, such as pain at the injection site, redness, fatigue, headache, chills, vomiting and fever.
