Are covid-19 vaccines worth getting if they’re not 100 percent effective?

Wang Huaqing, chief expert of the immunization program at the Chinese Center for Disease Control and Prevention, said the vaccine can only be approved if its effectiveness meets certain standards.

But the way to make the vaccine more effective is to maintain its high coverage rate and consolidate it.

Under such circumstances, the disease can be effectively controlled.

“Vaccination is a much better way to prevent a disease, to stop its spread, or to reduce its epidemic intensity.

Now we have the COVID-19 vaccine.

We started inoculation in key areas and key populations, aiming to establish immune barriers among the population through orderly inoculation, so as to reduce the transmission intensity of the virus, and finally achieve the goal of stopping the epidemic and stopping the transmission.

If everyone think now of the vaccine is not one hundred percent, I don’t getting a vaccination, it can’t build up our immune barrier, also can’t build up immunity, once there is the source of infection, because the vast majority have no immunity, the disease occurs in popularity, are also likely to be spread.

In fact, the epidemic and the spread of the emergence of measures to control it, the cost is very large.

But with the vaccine, we give it early, people are immunized, and the more we give it, the more immune barrier is built up, and even if there are scattered outbreaks of the virus, it doesn’t become a pandemic, and it stops the spread of the disease as much as we would like.”Wang Huaqing said.

Mr Wang said, for example, such as measles, pertussis is strong two infectious diseases, but through vaccination, by very high coverage, and consolidate such high coverage, has made these two diseases is well controlled, the measles incidence of less than 1000 last year, reached the lowest level in history, pertussis has fallen to a low level, All of this is due to the fact that through vaccination, with high coverage, the immune barrier in the population is secured.

Recently, the Ministry of Health of Chile published a real world study of the protective effect of the Sinovac Coronavirus vaccine, which showed a preventive protection rate of 67% and a mortality rate of 80%.
