People ages 65 years and older have the option to receive 1 additional bivalent mRNA vaccine doseįor people who are moderately or severely immunocompromised:.People ages 6 years and older who are unvaccinated or previously received only monovalent vaccine doses are recommended to receive 1 bivalent mRNA vaccine dose.At the time of initial vaccination, depending on vaccine product, children ages 6 months–4 years are recommended to receive 2 or 3 bivalent mRNA vaccine doses children age 5 years are recommended to receive 1 or 2 bivalent mRNA vaccine doses.
The number of bivalent doses varies by age, vaccine, previous COVID-19 vaccines received, and the presence of moderate or severe immune compromise.įor people who are not moderately or severely immunocompromised: Overview of the COVID-19 vaccination scheduleĬDC recommends that people ages 6 months and older receive at least 1 bivalent mRNA COVID-19 vaccine.Īn overview of COVID-19 vaccination is summarized below detailed schedules can be found in Table 1 for people who are not moderately or severely immunocompromised and in Table 2 for people who are moderately or severely immunocompromised.
See Appendices A ( People who received COVID-19 vaccine outside the United States) and B ( People who received COVID-19 vaccine as part of a clinical trial) for recommendations for these populations.
CDC recommends that people stay up to date with COVID-19 vaccination. There is currently no FDA-authorized COVID-19 vaccine for children younger than age 6 months.

COVID-19 Vaccine Product Information can be consulted for a full list of ingredients and information on the conditions of use, storage and handling, preparation, and administration procedures.ĬOVID-19 vaccination is recommended for everyone ages 6 months and older in the United States for the prevention of COVID-19. None of the currently FDA-authorized COVID-19 vaccines are live-virus vaccines.ĬOVID-19 vaccine-specific FDA fact sheets and U.S. Janssen COVID-19 Vaccine is no longer available in the United States. Novavax COVID-19 Vaccine is formulated as a monovalent vaccine based on the original (ancestral strain) of SARS-CoV-2. The monovalent formulations of the two mRNA COVID-19 vaccines (COMIRNATY/Moderna COVID-19 Vaccine and SPIKEVAX/Pfizer-BioNTech COVID-19 Vaccine) should no longer be used for COVID-19 vaccination.Īll currently available mRNA COVID-19 vaccines in the United States are formulated as a bivalent vaccine based on the original (ancestral) strain of SARS-CoV-2 and the Omicron BA.4 and BA.5 (BA.4/BA.5) variants of SARS-CoV-2. Pfizer-BioNTech COVID-19 Vaccine, Bivalent.Last May, Novavax told investors it expected to file for the FDA's authorization "in the third quarter of 2021." Over the summer, the company disclosed the Biden administration had paused funding for Novavax's manufacturing until it could strike an agreement with the FDA over "analytic methods" for its vaccine.The following COVID-19 vaccines, categorized into three vaccine types, are currently authorized under an EUA by FDA and available for use in the United States: However, the company's submission comes later than initially hoped for. Novavax also says its vaccine should work against the Omicron variant, citing data from booster and adolescent studies. The company has touted results showing the vaccine was safe and effective at curbing infections - around 90% overall - in published findings of clinical trials of its doses in North America and the United Kingdom earlier in the pandemic. The vaccine has also been greenlighted by the World Health Organization, manufactured by sites in Europe and India. Novavax's shot has already won regulatory approvals in several countries around the world, including Australia and South Korea this month. This is different from the mRNA vaccines or Johnson & Johnson's Janssen "viral vector" vaccine, which work by getting some of the body's cells to produce a harmless portion of SARS-CoV-2, the virus that causes COVID-19, in order to trigger an immune response. Protein vaccines like Novavax's doses are also combined with ingredients called adjuvants that can stimulate the body to train a better immune response. The technique has been used for years in vaccines against hepatitis B, pertussis (whooping cough) and other diseases. Unlike traditional vaccines, which rely on injecting a dose of the entire disabled or weakened virus, scientists developing protein subunit vaccines pick out only specific fragments of the virus to trigger an immune response. Of the portfolio of vaccines whose development was backed by the Trump administration's Operation Warp Speed early in the pandemic, two - Novavax's shots as well as another developed by Sanofi Pasteur and GlaxoSmithKline - are protein-based.
