Vitamin-D Does Little To Prevent Or Treat Covid-19

A large randomized trial investigated whether vitamin D3 supplementation can improve the course of COVID-19. The study included 1,747 people who had recently been diagnosed with COVID-19 and their household contacts. Participants were given either high doses of vitamin D3 for one month or a placebo.
The results showed that vitamin D did not reduce how often patients needed healthcare, such as hospital visits, emergency room visits or doctor visits. It also did not reduce the severity of symptoms, and it did not affect the risk of family members in the same household becoming infected.
However, the researchers saw a slight trend towards fewer persistent symptoms after two months in those who received vitamin D. Around 21% in the vitamin D group reported long-term symptoms compared to 25% in the placebo group. However, the difference was small and not statistically significant.
The researchers therefore believe that vitamin D is unlikely to reduce acute illness or the need for care in COVID-19, but that it may be worth studying further whether vitamin D can affect the risk of long-term symptoms after infection. No safety concerns with the treatment were reported.

Aftermath Autoimmune Immune system Psoriasis Symptoms The Virus

Psoriasis Turns Serious From Covid-19

The article describes an unusual but serious case in which a person with a pre-existing inflammatory disease (psoriasis) became severely impaired after a covid-19 infection.
After the person had covid, a high fever, severe skin rashes and a general deterioration in condition quickly developed. It turned out to be a severe form of psoriasis that can affect the entire body and in some cases become life-threatening. This type of deterioration is unusual but known in medicine.
The researchers explain this by how the immune system reacts. Covid-19 can affect the immune system for a long time, even after the infection itself has passed. In some people, this can lead to the immune system becoming overactive and starting to drive inflammation in the body. If you already have an inflammatory disease, it can then flare up severely.
They point out in particular that certain immune cells and signaling substances in the body can increase after the infection, which can create an imbalance that triggers the disease. So it is no longer about the virus itself, but about how the body reacts afterwards.
The conclusion is that in some cases, COVID-19 can act as a trigger for serious inflammatory conditions, especially in people who already have a vulnerability. This does not mean that this is common, but it shows that the infection can have more long-term and complex effects than just an acute respiratory illness.

Antivaxx Misinformation On The Rise Again

The WHO warns that misinformation about vaccines is on the rise again. This is making more people unsure or negative about vaccination, which could lead to fewer people getting vaccinated.
At the same time, resources for research are decreasing, which could slow the development of new vaccines.
Vaccines have saved over 150 million lives in the past 50 years, but if trust continues to decline, there is a risk that diseases that were previously under control will start to spread again.
Therefore, the WHO emphasizes that it is important to counter misinformation and strengthen trust in vaccines.
