Vaccination and options
07
Dec
The UK starts its mass vaccination on Tuesday, which will be 40 
million vaccines for 20 million people, due to the need for two doses of the Pfizer vaccine.
The effectiveness is around 95% and the side effects in about 2% of the volunteers are headaches and fatigue, similar to a strong hangover, however there will be other vaccine options.
Differently in Brazil, the options are small and the effectiveness of the vaccine, despite all the political propaganda surrounding the federal government’s AstraZeneca / Oxford vaccine and the São Paulo government’s Coronavac, both are much less efficient and have popular distrust.
State and municipal health secretaries published on Saturday (5/12) on the website of the Brazilian National Council of Health Secretaries (Conass) a request that the federal government acquire all vaccines against Covid-19 with proven efficacy and safety, economic interests / politicians must unfortunately prevail and we will be left with few options.
What leads us to distrust political and economic interests is the disregard for efficiency.
Two reasons are important in terms of efficiency (it is different from effectiveness), the first is that which mobilizes the natural system we have (the majority representatives are macrophages) and that develops a defense independent of the infectious agent, the second and second if the system is not enough (see su-efficient root) it mobilizes the adaptive or acquired immune system, which is more sophisticated and dependent on the type of bacteria or virus, this system must “generate” defenses (the most representative are the lymphocytes).
What proves that this is true is that all the agencies say that there is no guarantee of the end of the pandemic, and we must remain taking care of protection, time will tell and it will not cost more lives.
