A year ago today, Margaret Keenan was the first in the world to receive the Pfizer / BioNTech covid-19 vaccine outside of clinical trials. Twelve months later, billions of injections have been given, and some countries have already received a third coronavirus vaccination.

The astonishing development of the covid-19 vaccine in 2021 shows some of the best and worst aspects of modern medicine. It is now estimated that nearly 8 billion doses have been applied to people’s arms in the last 12 months. This is an incredible effort by medical services around the world. However, the vaccine is not evenly distributed. Many people in high-income countries receive three jabs by Christmas, but it is estimated that only about five percent of people in low-income countries will receive at least one jab by the end of the year.
On December 8, 2020, Margaret Keenan of the United Kingdom The first person in the world to receive the Pfizer / BioNTech vaccine Out of clinical trials. However, immunization began in January 2021 in the United Kingdom and other wealthy countries, and due to limited initial supply, shots had to be prioritized in the most vulnerable countries.
The figures for the actual efficacy of the vaccine are promising. In the UK, two shots of the Oxford / AstraZeneca or Pfizer / BioNTech versions reduced infection with the Delta variant. 67% and 80% respectively, Hospitalization is 92% and 96%, death is 91% and 90%.If the vaccinated person becomes infected, they 63% less likely to infect the virus To others.These numbers are Omicron variant..
There were serious but rare side effects of vaccination. In March, it became clear that the Oxford / AstraZeneca vaccine could cause a blood coagulation syndrome called vaccine-induced immunothrombotic thrombocytopenia (VITT). This also turned out to be related to the Johnson & Johnson vaccine. Man.
In June, it was revealed that the Moderna and Pfizer / BioNTech vaccines can cause an inflammation of the heart called myocarditis. This is common in young people, especially men, The incidence of myocarditis after covid-19 itself is 6 times higher..
In the last few months of 2021, wealthy countries provided vaccine doses to children under the age of 16, and in some countries, such as the United States, For children up to 5 years old.. In addition to this, the promotion of third or booster shots laid the foundation for Israel’s efforts to tackle the Delta variant and the UK’s plan to overcome the difficult winter and prepare for the Omicron variant.
The vaccine also allowed countries that took a stricter approach to pandemic management from the beginning to begin resuming after a long blockade. For example, New South Wales, Australia, has kept its promise to ease regulations, including Sydney, after 70% of people over the age of 16 have been fully vaccinated.
However, plans for rich countries to support low-income countries through a vaccine delivery coalition called COVAX are expected by high-income countries buying large stocks for themselves and export bans in India. It progressed slowly, partly because it stopped. A big maker there. “We ran into a lot of problems,” says Seth Berkley of Gavi, one of the organizations that leads COVAX.
On the other hand, in high-income countries with abundant supply, a small number of people are still resisting vaccination, mainly because of misconceptions about side effects. It helps promote the circulation of the virus in the community and is vaccinated, but still endangers the lives of vulnerable people due to poor age and health.
