Vaccine: Doses and Process

Why would I need a booster shot?

Updated June 30, 2022

Protection against severe illness, hospitalization, and death from Covid-19 wanes with time in those who have received the primary series of the Pfizer, Moderna, or Johnson & Johnson vaccine. This reduction in protection occurs particularly in older individuals. A booster dose of vaccine stimulates the immune system to reestablish protective levels of immunity.


What should I do if I get ill in between doses?

If you experience a severe allergic reaction, call 911, or go to the nearest hospital.

Call Stamps Health Services (students) or your healthcare provider (faculty/staff) if your illness seems to be more than mild to moderate expected side effects of the vaccination.

As part of this vaccination program, Stamps Health Services is required to report serious adverse events (irrespective of whether they are caused by the vaccination) after vaccination, which include death, a life-threatening event, inpatient hospitalization or prolongation of an existing hospitalization, a persistent or significant incapacity or significant disruption of the ability to conduct normal life functions, a congenital anomaly or birth defect, or an important medical event that based on medical judgment may jeopardize the individual and may require medical or surgical intervention to prevent one of the outcomes above. Any event meeting these criteria should be reported to Stamps Health Services.

You may also be given an option to enroll in v-safe. V-safe is a new voluntary smartphone-based tool that uses text messaging and web surveys to check in with people who have been vaccinated to identify potential side effects after Covid-19 vaccination. V-safe asks questions that help the CDC monitor the safety of Covid-19 vaccines. V-safe also provides second-dose reminders if needed and live telephone follow-up by CDC if participants report a significant health impact following Covid-19 vaccination.

Do I have to get both doses from Georgia Tech?

No, it is not necessary to get both doses from Georgia Tech.

It is important to note that Georgia Tech is administering only the Pfizer-BioNTech vaccine in the vaccination clinic and is opening appointments based upon supply.

All doses of the Moderna vaccine have been administered or reserved for second doses — no additional appointments will be made available for the Moderna vaccine.


Will I get a reminder when it is time for my second dose?

Those who received their first dose at Georgia Tech will receive a direct communication from Stamps Health Services with instructions for scheduling your second appointment.

We will reserve slots on for second dose vaccinations. To ensure you receive your second dose at Georgia Tech, you must act promptly once you receive notification about scheduling the second dose. Unclaimed appointment slots will be opened to all who are eligible.

Individuals who received their first vaccine dose at a location other than Georgia Tech should submit a ticket to to notify the vaccine team that you need a second dose.


If I receive a Pfizer-BioNTech Covid-19 vaccine for my first dose, can I receive a Moderna Covid-19 vaccine for my second dose or vice versa?

Updated November 11, 2021

No. The vaccines are not interchangeable and both doses must match. Your vaccine card will specify the type of vaccine you received and when you received it.

New guidance from the FDA and the CDC does allow you to receive a booster dose that is different from the initial two doses of vaccine. Any vaccine can be given as the booster dose. For instance, if you received two doses of Moderna vaccine initially, you can get a booster dose with the Pfizer vaccine.
