The “COVID-19– Post-Covid Syndrome” pandemic has raised many health issues for all 205 countries affected by the pandemic to a greater or lesser extent. At the same time, it was found that vaccination of the population of different countries did not bring the expected results, as it was with vaccination against poliomyelitis, measles or smallpox viruses. The World Health Organization (WHO) has yet to give a full analysis of the pandemic, but some of the lessons learned by National health centers (Ministries) are already clear. First, many countries have described cases of severe post-vaccination complications, including deaths. Cases of stillbirth with vaccination of pregnant women are reliably shown.
