What is a bivalent?
Listen to pronunciation. (by-VAY-lent vak-SEEN) A vaccine that works by stimulating an immune response against two different antigens, such as two different viruses or other microorganisms.
Who makes the bivalent booster?
The only bivalent boosters authorized are mRNA versions manufactured by Pfizer-BioNTech and Moderna. The U.S. government has bought 171 million bivalent vaccine booster doses—66 million from Moderna and 105 million from Pfizer.
How long has the mRNA vaccine been around?
mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV). As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine.
Will a COVID-19 vaccine alter my DNA?
No. COVID-19 mRNA vaccines do not change or interact with your DNA in any way.
What is the bivalent COVID-19 booster shot?
The FDA has authorized an updated COVID-19 booster that offers improved protection against recent variants. The new booster is bivalent, providing better protection against both the original strain of COVID-19 and the Omicron variants that are currently causing most infections (BA.4 and BA.5).

Has the mRNA vaccine been used before COVID-19?
Prior to the COVID-19 pandemic, mRNA vaccines targeting infectious diseases including HIV-1, rabies, Zika and influenza were already in clinical trials, as were mRNA vaccines targeting multiple hematologic and solid organ malignancies (Pardi, 2018).
Do COVID-19 mRNA vaccines have long-term effects?
The Pfizer and Moderna vaccines were created using messenger RNA (or mRNA) technology, which has been used for about 10 years in cancer treatment, with no long-term effects detected. And even before that, scientists had been working with mRNA technology for years. 3. mRNA technology does not alter your DNA.

These newly authorized shots are reformulated versions of the Moderna and Pfizer-BioNTech COVID-19 vaccines and theyre available at pharmacies, clinics and doctors offices around the country.
How was the COVID-19 vaccine developed so quickly?
Scientists began work on the COVID-19 vaccine in January 2020. Dedicated vaccine funding helped move vaccine candidates through the pre-clinical/clinical assessments and trials both quickly and thoughtfully. This has enabled researchers to advance into phase 3 clinical trials (testing the vaccine on large groups of people to evaluate safety and effectiveness) in six months instead of the typical two years. The vaccine was mass produced before the clinical studies were complete to save time.
Are long term side effects possible with the COVID-19 vaccine?

These cases typically occur in male adolescents and young adults after the second dose, and within a week of vaccination. It is important to seek medical care if symptomatic (chest pain, shortness of breath, having a fast beating, fluttering, or pounding heart).
What are some of the long-term side effects of COVID-19?
The effects of COVID-19 can persist long after the initial symptoms of the illness are gone. These effects, called post-acute sequelae of COVID-19 (or PASC), can include brain fog, fatigue, headaches, dizziness, and shortness of breath.
Who qualifies for new bivalent COVID-19 booster?
Adults 18 years or older can get the Moderna booster, while the Pfizer-BioNTech version has been authorized for people 12 and up. In both cases, a person is only eligible for a booster if it has been at least two months since their last COVID vaccine.

Are COVID-19 vaccines safe even though the vaccines were developed rapidly?
See full answerAlthough COVID-19 vaccines were developed quickly, research and development on vaccines like these have been underway for decades. All vaccine development steps were taken to ensure COVID-19 vaccine safety and effectiveness, including:
- Clinical Trials – All vaccines in the United States must go through three phases of clinical trials to ensure they are safe and effective. The phases overlapped to speed up the process, but all phases were completed.
- Authorization or Approval – Before vaccines are available to people, the U.S. Food and Drug Administration (FDA) reviews data from clinical trials. FDA has determined three COVID-19 vaccines meet FDA’s standards and has granted those vaccines Emergency Use Authorizations (EUAs)external icon or full FDA approval.
