Beginning to take shape is a more comprehensive picture of what has come to be known as protracted COVID-19, which should someday enable researchers to treat symptoms that can ruin people's lives for months or years following a COVID-19 infection.

While I didn't hesitate to get the Covid-19 vaccine, my family was anxious about it, even though I’m no longer a minor. Other parents probably feel the same way. After all, we can’t help but wonder if it’s really necessary to inject a bioactive substance into our body — much more into our child’s body — when there might be no need for it. But others may feel relieved, knowing that their child can return to some level of normalcy after getting vaccinated.

Only after the Covid-19 mRNA vaccines were distributed to the public did we learn it can cause myocarditis (inflammation of heart muscles) in rare cases. It was rare enough that it escaped statistical detection in the initial randomized clinical trials (RCTs).

On the one hand, cancer patients are advised to get more shots of the Covid-19 vaccine because of their weakened immune systems. On the other hand, precisely because of their weakened immunity, unnecessary vaccinations may put more burden on the immune system, a fewexpertstheorized.

Millions of Americans congregated in homes and places of worship without masks this month for Passover, Easter, and Ramadan — the most recent proof that coronavirus has faded from public consciousness as the pandemic comes to an end.

Rep. Brad Wenstrup, R-Ohio, who chairs the House Select Subcommittee on the Coronavirus Pandemic, received an email from a representative of the Chinese Embassy in the US indicating China's "grave concern" on an impending inquiry on the COVID-19 sources.

Age represents the number one risk factor for severe Covid-19. “Adults over 65 years of age represent 80% of hospitalizations and have a 23-fold greater risk of death than those under 65,” Harvard researchers stated in a published review in Aging.

The novel coronavirus is just one in a long list of viruses that have jumped from animals to humans, causing significant harm. HIV, Ebola, swine flu, bird flu, SARS, and MERS are all examples of these zoonotic diseases. With climate change, wildlife exploitation, and unsustainable farming practices disrupting habitats, the risk of more animal-borne diseases impacting human populations is only expected to rise. To address this growing concern, an international team led by San Diego Zoo Global researchers has proposed routine testing of animals for viruses in potential disease hotspots, focusing on local surveillance and decentralizing monitoring efforts.

A syndrome is a collection of symptoms of unclear causes, which is different from a disease with a defined set of symptoms and a cause. For example, Covid-19 is a disease of the lower respiratory tract that’s caused by a virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In contrast, long-COVID is a syndrome involving multiple organ systems and biological causes.

On one hand, cancer patients are advised to get the Covid-19 vaccine because of their weakened immune systems. On the other hand, precisely because of their weakened immunity, unnecessary vaccinations may simply put more burden on the immune system.

A few researchers have previously raised the hypothetical concern of the Covid-19 mRNA vaccine, encapsulated in lipid nanoparticles (LNPs), entering the brain, given that LNPs can be used to deliver medical drugs across the blood-brain barrier (BBB) into the brain.
