When you get infected with the coronavirus, your immune system mounts a series of responses that bulk up the bodys defenses against future infections. If a patient accidently received a monovalent mRNA vaccine for the booster dose, the dose generally does not need to be repeated. People who were fully vaccinated within three months of the exposure. No, the monovalent mRNA vaccines (i.e., Moderna or Pfizer-BioNTech) are not authorized for use as a booster dose; they can only be used for the primary series.

Vaccine effectiveness might also be increased with an interval longer than 3 or 4 weeks. My patient is moderately or severely immunocompromised and previously received EVUSHELD. No, children ages 6 months4 years who have completed the 3-dose Pfizer-BioNTech primary series with monovalent vaccine cannot get a dose of bivalent Pfizer-BioNTech vaccine. Thus, ritonavir-boosted nirmatrelvir should not be given within 2 weeks of administering a strong CYP3A4 inducer (e.g., St. Johns wort, rifampin). However, there are additional considerations for Moderna, Novavax, and Pfizer-BioNTech COVID-19 vaccines if administering an orthopoxvirus (monkeypox) vaccine. Do not revaccinate for the monovalent mRNA booster dose(s). And when is the optimal time to get it? Stader F, Khoo S, Stoeckle M, et al. Coadministration of ritonavir is required to increase nirmatrelvir concentrations to the target therapeutic range.
