The first possible signs of improvement because of the vaccine might be already noticeable in Israel. Furthermore, some countries are good and others are bad about vaccinating their own populations.
The vaccination program in many countries is going very bad. From the 17 monitored countries, only the US has 7.05 million people vaccinated, China 4.5 million, the UK with 1.5 million and Israel 1.2 million. The rest of the countries much less. Worldwide, 18.9 million people are vaccinated for the COVID-19 virus, 0.24% of the world population, 523,836 people per day. Only Israel has 13.5% of its population vaccinated This is interesting, because we can see if the vaccine has already some effects on the mortality numbers.
