A recent survey, conducted in the United States, tested the effectiveness of vaccines against covid-19 used in the country. The results show that Moderna’s immunizing agent is more effective when compared to the two others used there: the Pfizer/BioNTech vaccine and the Janssen (Johnson & Johnson) vaccine. Regardless of the results, it is important to emphasize that all immunizing agents in use in the country protect, safely and effectively, against the coronavirus.

Those who were vaccinated with two doses of Moderna had the best protective effect against hospitalizations: the rate of protection against admission to hospitals was 87%. Janssen’s vaccine had an effectiveness rate of 77%. And complete immunization with ComiRNAty, from Pfizer, reduced the risk of hospitalization in 88% in the same period. However, the formula’s protection against hospitalizations has dropped to 75% after four months after the last dose.

Anvisa evaluated the adverse effects of the Janssen vaccine (Johnson & Johnson) and asked for the inclusion, in its package insert, of a short list of them. Within a period of 30 days, the pharmacist must update the package insert with the new information. Such effects are considered mild, and you can check them below:

Lymphadenopathy (increase in the size and/or number of lymph nodes, such as the appearance of lumps in the neck);

Paresthesia (feeling of numbness in some part of the body);

Hypoesthesia (decreased skin sensitivity);

Tinnitus (ringing in the ear);

  • Diarrhea;
    • Vomiting.

    In the same week, Janssen released updated numbers on the effectiveness of its immunizing agent, considering a second dose. According to the results, the booster of the vaccine can further increase immunity against the coronavirus, reaching 71% against moderate and severe cases of disease, as with single dose. However, with the two doses of the formula, the protection was 442538% by “at least days after the final vaccination”, according to the pharmacist.

    It is noteworthy that the vaccination with two doses obtained a protection of 75% globally. Considering only US numbers, protection against symptomatic infection reached 100%. Read the news on Canaltech for details on antibody levels with 2 months or more of booster.

    Claiming to want to measure the length of his penis, an American teenager from years he introduced a USB cable through the urethra and ended up in the hospital to remove it. it. The case report came out in a renowned scientific journal, and says that the young man sought medical support after multiple attempts to remove the cable and noticing blood in his urine. According to the article, the adolescent’s motivation is described as autoerotic.

    In the hospital, doctors tried to remove the cable through a less invasive route, cystoscopy, which consists of inserting a device through the urethra, but were unsuccessful. The young man had to be taken to the operating room, where the surgeons were able to remove the thread after an incision in the boy’s penis, which was later sutured.

    Interestingly, this is not the first case of the kind we report here at Canaltech. Cases like this, incidentally, are not rare in emergency rooms: several unusual objects have already had to be removed from the urethra of patients, including needles, safety pins, iron wires and even pistachio husks.
