Vaccines have been studied in biology textbooks in senior high schools, which is one of the great inventions discovered by modern humans. Injecting some viruses with weak toxicity into human body is very similar to some viruses with strong toxicity, so that human body can produce antibodies, thus lifelong immunity to such viruses is self-evident. Smallpox virus, the most harmful virus in human history, has been eliminated.
However, these people think that vaccines are a means used by high-level officials to control others, and they inject things that do not belong to them into the human body. Who can guarantee that nothing will happen? Bill Gates said earlier that in order to protect all mankind, everyone in some African countries should be vaccinated. Conspiracy theorists? It should be taken for granted that those people finally gave away the clues. This is the evidence that Bill Gates wants to control blacks and is unwilling to get vaccinated.
However, according to epidemiology, if all human beings want to be immune, a large number of people will inevitably produce antibodies, and the virus will not spread among people. To this end, Italian Rep. Lisa? Noah also launched a signature campaign that vaccination is everyone's responsibility and no one has the right to choose whether to vaccinate or not. He also called on everyone to put pressure on the government to let more people get the COVID-19 vaccine. Of course, other countries will also sell vaccines to Europe, but they don't insist. Mainly depends on whether the government cares about public opinion. Perhaps European governments still choose to hoard vaccines and take them out when the epidemic is serious. There may be less opposition then.
