A third dosage of a vaccine, also known as a booster dose or booster injection, is merely an extra dose of the vaccine that will help improve your immunity against a disease. Currently, there is a third booster dose available for the COVID-19 vaccination regime. Why is a booster dose of vaccine needed? A booster dose is needed for three reasons, according to experts: 1. To safeguard those who did not respond well to the first two doses, which may occur with certain immunocompromised individuals. 2. The immunity gained through vaccination may wane over time, therefore a booster dose is necessary to guarantee your protection. 3. The efficacy of prior vaccination doses against some of the new and emerging variants of concern may be insufficient While some of these scenarios are unlikely to arise at this time, booster shots, especially in vulnerable and high-risk groups, are highly recommended in anticipation of any potential possibilities. When should I receive the COVID-19 booster dose? It is recommended for the current target group to receive a booster shot 6 months after receiving the second dose. Who should receive a booster dose? The current recommendation is for Pfizer vaccine recipients aged 18 and above to receive a booster dose at least 5 months after receiving the second dose. Adults over the age of 60 should also receive the booster shot by February 2022, or their 'completely vaccinated' status will be removed. Who can receive the Pfizer booster shot? Adults aged 18 and above who fulfil the criteria are eligible to receive a Pfizer booster dose. What is the efficacy of the Pfizer booster dose? Studies indicate that a third dose of the Pfizer vaccine increases the neutralising antibody by 25x compared to two doses against the emerging Omicron variant. Is the Pfizer booster shot safe? What are the possible side effects? The side effects of the Pfizer booster shot are similar to the initial doses. These include redness, pain and swelling at the site of injection as well as headaches, muscle aches, fatigue, chills, fever and nausea. These symptoms are normal signs that the body is responding to the vaccine and should subside after a few days, if not less. Can I get the Pfizer vaccine as a booster/3rd dose if I get a different vaccine brand in the previous dose/doses? Yes, the Pfizer vaccine has been approved as a booster shot for recipients of other vaccine brands such as Sinovac. How long would the Pfizer booster dose/3rd dose remain effective? Will booster shots be required every year for Covid? At the current stage of the pandemic, there is still more to learn regarding the frequency of receiving a COVID-19 booster shot. There have been no concrete guidelines established as of yet. However, experts are studying the patterns and requirements, and any definite evidence can only be drawn after extensive studies ## COVID-19 Vaccination in Malaysia [AstraZeneca Vaccine](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/astrazeneca-covid-19-vaccine) [AstraZeneca Vaccine Booster](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/astrazeneca-covid-19-vaccine-booster) [CanSino Vaccine](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/cansino-covid-19-vaccine) [CanSino Vaccine Booster](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/cansino-covid-19-vaccine-booster) [Pfizer Vaccine](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/pfizer-covid-19-vaccine) [Sinovac Vaccine](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/sinovac-covid-19-vaccine) [Sinovac Vaccine Booster](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/sinovac-covid-19-vaccine-booster) [COVID-19 Vaccination at Home (Sinovac Single or Booster Dose)](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/sinovac-covid-19-booster-vaccination-at-home) [COVID-19 Vaccination at Home (Sinovac Dose 1 & 2)](https://www.doctoroncall.com.my/medicine/covid-19-vaccine/sinovac-covid-19-vaccination-at-home) [![DOC AI](https://storage.googleapis.com/doc-cdn/medicine/ai-chatbot.webp)](https://ai.doctoroncall.com/chatbot/a2381046-db3d-4fd6-9fa5-7db713e9ace5) [![DoctorOnCall logo](https://storage.googleapis.com/doc-cdn/home/DOC%20logo%20.svg)](https://www.doctoroncall.com.my/) DoctorOnCall is Malaysia's most complete digital healthcare platform to access clinics, pharmacies, hospitals and health laboratories online.
