The World Health Organization’s chief scientist on Monday advised against people mixing and matching COVID-19 Vaccine from different manufacturers. They are calling it a dangerous trend since there was little data available about the health impact.Soumya Swaminathan said that it is a little bit of a dangerous trend here. We are in a data-free, evidence-free zone as far as to mix and match. It will be a chaotic situation in countries if citizens start deciding when and who will be taking a second, a third and a fourth dose.
We have four countries that have announced a booster program, and a few more that are thinking about it. If 11 high and upper-middle-income countries decide that some of them are large countries, they will go for a booster for their populations or even subgroups. This will require an additional 800 million doses of the COVID-19 Vaccine.
Tom McMillan, Alberta Health spokesperson said in a statement that the province’s advisory committee on vaccines has said second doses for COVID-19 Vaccine can be safely used interchangeably. Every Albertan who received different vaccines for their first and second dose should feel good that they are fully immunized and have the greatest protection against all strains of COVID-19. With COVID-19 still a crucial health threat around the world, we strongly recommend that everyone book the first appointment available, regardless of the type of vaccine.
