NATIONAL POLL: Do You Still Have Trump's Back 100%?

Israeli daily newspaper Davar reported:

The data show that the rate of reported side effects among women and young people is higher than among men and adults. In addition, the survey shows that about 10% of women aged 54-18 reported irregular menstruation, and in about half of them it lasted between two and three months of receiving the vaccine.


Two-thirds of respondents (66.4%) reported side effects near the vaccine. The survey shows that side effects were more common among women and young people: 75.4% of women reported at least one side effect close to the vaccine, compared with 57.7% of men. By age segmentation, 71.4% of respondents aged 39-18 and 69.9% of respondents aged 59-40 reported at least one side effect, compared with 57.2% aged 50 and over.

Nearly half (44.1%) of the respondents who reported suffering from any phenomenon after the vaccine also reported that as a result they had difficulty performing daily activities. Women reported this more than men (50.9% of the women who reported, compared to 35.4% of the women who reported). Individuals of all respondents (0.5%) who reported suffering from any phenomenon after the vaccine were hospitalized following the same phenomenon.

The most common side effects among women were menstrual irregularities. The most reported symptoms were delays in menstruation (37.8%), increase in menstrual bleeding (31.1%), premature menstruation (28.9%), longer bleeding duration (26.7%), and severe menstrual pains (20%).  
Israel was one of the first countries in the world to launch a national booster vaccination campaign; it began in August of last year. Nevertheless, so-called “breakthrough” infections continued to occur among those who received the top-up jabs. 
Within the first week of the booster campaign, Israeli news  reported  that 14 Israelis who received a third “booster” dose of the Pfizer vaccine had tested positive for COVID.
