AstraZeneca Vaccine : Can You Ask For Earlier Second Dose?

Health authorities are delaying the second AstraZeneca vaccine dose to 12 weeks, but can you ask for an EARLIER second dose? Should you?


AstraZeneca Vaccine : Can You Ask For Earlier Second Dose?

As we reported earlier, the second dose of the AstraZeneca COVID-19 vaccine has been set at 12 weeks in Malaysia, as it is in many other countries.

But you can ask to receive the second AstraZeneca dose earlier than 12 weeks, if for example, you need to travel for work or studies.

The option is not there yet, but it will be made available on the Vaksin COVID website soon.


AstraZeneca Vaccine : Will Earlier Second Dose Reduce Efficacy?

The short answer is yes, an earlier second dose will reduce efficacy for the AstraZeneca vaccine.

A study under review at the Lancet found that the UK approach of delaying the second dose until 12 weeks / 3 months later made the vaccine more effective!

In light of the UK results, the WHO changed its advisory on the AstraZeneca vaccine, to recommend that the second dose be given 8 to 12 weeks after the first dose.

Second Dose
Less Than 6 Weeks 54.9%
12 Weeks Or More 82.4%

But do not worry if you need to take your dose a little earlier at 8 weeks. These efficacy results are looking at symptomatic COVID-19 – including those with mild symptoms.

Even the first dose alone will greatly protect you against hospitalisation and death! The second dose just gives you an extra boost against mild or asymptomatic COVID-19!

So please try and get vaccinated before you travel, even if it means taking the second dose earlier. Some protection is better than no protection at all!
