With 1.27 million doses administered and 601, 000 fully vaccinated, the island’s current fully vaccination rate of stands at 20.3 per cent. With at least 201 countries commencing the vaccination process, Jamaica has one of the lowest rates in the world, ranking as the 8th lowest country according to Statista.

With the Health Ministry having to dispose of hundred of thousands of vaccine doses, the current low vaccine take-up may be attributed to ignorance among the Jamaican public.

In the last of Our Today‘s COVID vaccine ‘need-to-know’ series, the focus will be on the Pfizer vaccine, where information from both the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) will be utilised.

It is highly recommended to use the same Pfizer vaccine for the second dose, however if there is an issue with product availability, the AstraZenca or single dose vaccine can be used for the second dose.

The Pfizer vaccine has also approved for use as the second dose given after the inactive Sinopharm vaccine.
