You might not know it, but vaccines save 2-3 million lives a year around the world . Or 8,200 people per day, 340 people per hour, 5 people per minute . Just that.This makes the vaccine the best medicine in human history. Eh yes.
How does a vaccine work? Basically, a vaccine is a disease. It is a small piece of attenuated virus that is injected. And like the body, it’s a great machine, it defends itself when attacked . This is called the immune system. And that’s how we create antibodies. Basically guys who can smash the real virus when it really pops up. And there you have it, how we become immune to a virus!
So the vaccine does not cure everything, but it still heals all that (among others):
The yellow fever
The gastroenteritis rotavirus
Yes, that’s a lot. And yet we did not put everything. ” It is one of the most effective and cost-effective public health interventions in the health field ,” said the WHO, the World Health Organization.
But then why are there still diseases?
Good question. This is because of the “vaccine coverage.” Basically, it’s the proportion of people vaccinated in a population. And it is very important. For this to work, so that the virus does not spread, we must reach the figure of 95%. This is called “collective immunity” (a bit like the Koh-Lanta totem pole ). In France, a country of human rights, the rate was only 87% in 2019.
But the problem today is that there are people who don’t “believe” in vaccines. That is to say ? In France, 78% of the population has a favorable opinion on vaccines. It is less than in 2000. To fight against that, in our country, the vaccines are obligatory and all the children born after January 1, 2018 are subjected to it. A vaccine has two objectives: to protect oneself, but also to protect those around us. It’s a bit like on the road.
