COVID-19 Vaccination and Booster Recommendations

Primary Vaccination Series Recommendations

The Centers for Disease Control and Prevention (CDC) recommends a primary vaccination series for individuals, with specific dosing schedules for different age groups, including 2-dose Moderna (0, 4-8 weeks) or 3-dose Pfizer-BioNTech (0, 3-8, 11-16 weeks) for those aged 6 months-4 years, and 2-dose Moderna (0, 4-8 weeks) or 2-dose Pfizer-BioNTech (0, 3-8 weeks) for those aged 5-11 years, and 2-dose Moderna (0, 4-8 weeks), 2-dose Novavax (0, 3-8 weeks), or 2-dose Pfizer-BioNTech (0, 3-8 weeks) for those aged 12-17 years and adults aged ≥18 years 2
Immunocompromised individuals require additional doses in the primary series, as recommended by the CDC and supported by guidelines from the Praxis Medical Insights 1, 2

The CDC recommends that children aged 5 years should receive a Pfizer-BioNTech bivalent booster ≥2 months after primary series or monovalent booster, and children aged 6-11 years should receive either Moderna or Pfizer-BioNTech bivalent booster ≥2 months after primary series or monovalent booster, and adolescents aged 12-17 years should receive either Moderna or Pfizer-BioNTech bivalent booster ≥2 months after primary series or monovalent booster, and adults aged ≥18 years should receive either Moderna or Pfizer-BioNTech bivalent booster ≥2 months after primary series or monovalent booster 1

For adults who cannot or will not receive mRNA vaccines, the Novavax monovalent booster may be used if they completed any FDA-approved or FDA-authorized primary series, have not received any booster doses, and are unable or unwilling to receive an mRNA vaccine, as recommended by the CDC and supported by guidelines from the Morbidity and Mortality Weekly Report and Praxis Medical Insights 1, 3
Persons who recently had a SARS-CoV-2 infection may consider delaying a primary series dose or booster dose by 3 months from symptom onset or positive test result (if asymptomatic), as recommended by the CDC and supported by guidelines from the Morbidity and Mortality Weekly Report and Praxis Medical Insights 1, 3
Immunocompromised individuals may benefit from additional protection with Evusheld (tixagevimab and cilgavimab) administered every 6 months to supplement vaccine-conferred protection, as recommended by the CDC and supported by guidelines from the Morbidity and Mortality Weekly Report 3

Bivalent COVID-19 vaccine booster doses might improve protection against SARS-CoV-2 Omicron sublineages, as reported by the Morbidity and Mortality Weekly Report 4

Delaying vaccination beyond recommended timeframes may prolong the period of suboptimal protection, as noted by the Praxis Medical Insights 5
Using Janssen (Johnson & Johnson) vaccine except in very limited situations due to the risk for thrombosis with thrombocytopenia syndrome, as recommended by the CDC and supported by guidelines from the Morbidity and Mortality Weekly Report 2
Failing to recognize that immunocompromised individuals require special vaccination considerations, including additional primary doses, as recommended by the CDC and supported by guidelines from the Praxis Medical Insights 1
