The study of the coronavirus does not stop for a day, scientists are trying to learn as much as possible about it. The results of the latest investigation puzzled them – the effectiveness of vaccines for women and men is not the same.
The researchers found that coronavirus vaccines are more effective for men, and the results are “puzzling.” Usually the opposite happens – the female body gives a stronger immune response, reports Business Insider, citing the obtained data on the effectiveness of different types of vaccines:
Pfizer – 96.4% effective for men and 93.7% for women; Moderna – 95.4% for men and 93.1% for women; Johnson & Johnson – 68.8% for men and 63.4% for women.
Perhaps it’s all about high estrogen levels, suggests Sabra Klein, co-chair of the Johns Hopkins Center for Women’s Health, Sexual and Gender Studies, for other reasons. For example, gender characteristics. Women are more inclined to take care of their health, pay attention to symptoms of ailment, and do testing. And today the number of vaccinated among women and men is different – the number of the former prevails.
The age of patients with coronavirus after vaccination is also important – 47-70 years. The researchers speculate that the decline in vaccine efficacy rates in women could be due to menopause, which occurs between 40 and 60 years of age. However, the expert notes that additional research is required to establish a specific cause, which is ongoing.
Earlier, our publication, for example, wrote that the Swedish-British pharmaceutical company compared number of deaths after vaccinations with Pfizer and AstraZeneca in six European countries. The company’s internal report provides data that confirm that significantly more people died after vaccinations with Pfizer than after vaccination with AstraZeneca, RIA Novosti informs. In France, for example, the death rate is 45.3 per million after using Pfizer and 17.9 deaths after using AstraZeneca.
The report of the Swedish-British pharmaceutical company provides data on mortality per million vaccinated in other countries (the first figure for Pfizer, the second for AstraZeneca): Germany 29.9 and 6.5; Norway 164.3 and 44.6; Britain 20.7 and 24.2; Italy 10.9 and 7.3; Austria 47.5 and 7.5.
The vaccination campaign is active and successfully passes in all European countries, including in Greece… This is the only way to stop the march of COVID-19 across the planet. The milestone of 2 million vaccinations with two doses of coronavirus drugs was crossed in Greece yesterday.
