Why is the 4th dose Covid vaccine necessary?
The Covid-19 vaccine has proven effective in reducing illness, hospitalizations, and even preventing deaths caused by Covid-19. Currently, some countries around the world have started administering additional doses.
The World Health Organization (WHO) has compiled 7 studies on the efficacy of the 4th dose Covid vaccine. These studies include 6 from Israel and 1 from Canada. All of them were conducted during the rapid spread of Omicron globally. Although these studies vary in population and design, they all evaluated the effectiveness of the 4th dose Covid vaccine.
Among the 7 studies, 2 were conducted with healthcare workers in Israel. The first study concluded that the vaccine triggered a strong immune response without adverse effects. The second study surveyed individuals who had contracted Covid-19 after vaccination and compared them with those who received the 4th dose vaccine. The result showed a significantly lower Covid-19 infection rate among those who received the 4th dose compared to those who received only 3 doses.
