All COVID-19 vaccines provided by HCPH are free of charge. In most situations, Pfizer, Moderna, and Novavax COVID-19 vaccines are preferred over the Johnson & Johnson COVID-19 vaccine due to the risk of rare, but serious adverse events following administration of the J&J vaccine.

• The Moderna vaccine can be provided to individuals 6 months and older. Moderna is administered as a 2-dose primary series for most people or a 3-dose primary series for people who are moderately or severely immunocompromised.
• The Pfizer vaccine can be provided to individuals 6 months and older. Pfizer is administered as a 2-dose primary series for most people or a 3-dose primary series for people who are moderately or severely immunocompromised and children ages 6 months through 4 years old. Children ages 6 months through 4 years who have not yet completed their Pfizer primary series will receive a Pfizer bivalent vaccine as their third primary dose.
• The Novavax adjuvanted vaccine can be provided to individuals 12 years and older. Novavax is administered as a 2-dose primary series.

If you received your first dose of COVID-19 vaccine at another provider, you can still receive your second, additional, or booster dose at a vaccine site operated by Harris County Public Health (HCPH). To schedule your appointment, please call the HCPH Vaccine Hotline at 832-927-8787 or register online.

Residents who do not have access to a personal vehicle may still receive vaccines at HCPH vaccination sites. Please call the health department (i.e., Harris County Public Health, Houston Health Department) you registered with for alternative arrangements. For appointments with Harris County Public Health, call the HCPH Vaccine Hotline at 832-927-8787.

All of the vaccines being offered by Harris County are safe and effective at protecting people from getting seriously ill, being hospitalized, and even dying—especially when boosted. You can choose which COVID-19 vaccine to get depending on your age and preference. 

For adults ages 18 years and older, the mRNA COVID-19 vaccines (Pfizer-BioNTech or Moderna) and protein-based COVID-19 vaccine (Novavax) are preferred over Johnson & Johnson’s Janssen COVID-19 vaccine. The primary difference between these vaccines is that the Pfizer, Moderna, and Novavax vaccines require two shots whereas the Johnson & Johnson vaccine can be administered in one shot. Maximize protection and get all recommended vaccine doses and boosters as soon as possible.

Currently, the Pfizer & Moderna COVID-19 vaccines are the only COVID-19 vaccines available to children 6 months to 11 years old.
