First exposure to SARS-CoV-2 ‘locks in’ our #immuneResponse

yes, I would expect that the global exposure to covid and its vaccines may make it harder for any future #SARS-like #zoonotic outbreaks to cause harm.

Here’s why we don’t have a cold #vaccine. Yet.
Technically, #colds are #infections that affect your nose and throat, causing symptoms like sneezing, coughing, and generally feeling like garbage. Unlike some other infections they aren’t defined by the specific #virus that causes them. That’s because there are a lot of viruses that cause colds, including #rhinoviruses, #adenoviruses, and even seasonal #coronaviruses

#disease #coronaviruses #Wuhan

"New research out this month showcases the ever-present danger posed by coronaviruses, the family of viruses that gave rise to the covid-19 pandemic. Scientists in China have reportedly found a new coronavirus in bats that may be capable of spilling over and infecting humans.

Researchers at the Wuhan Institute of Virology led the study, published last week in the journal Cell. In lab experiments, the virus appeared to possess a key adaptation that allows it to infect a broad range of mammals, humans included. Other factors are present that make the virus less suited to humans for now, but the scientists say their discovery highlights the importance of studying these sorts of potential threats."

BCoV-Eri is to some extent prevalent in wildlife asylums. Given that S protein of BCoVs-Eri is highly variable & that some sites of this protein evolve under positive selection pressure, these strains could potentially acquire a favourable feature for cross-species transmission.

#SARS-CoV-2 and Other #Coronaviruses in #Rats, #Berlin, #Germany, 2023, Emerg Infect Dis.: https://wwwnc.cdc.gov/eid/article/30/10/24-1079_article

We tested 130 rats captured in Berlin for coronaviruses. SARS-CoV-2 #antibodies were detected in 1 rat, but all animals were negative by reverse transcription PCR, suggesting SARS-CoV-2 was not circulating in the rat population. However, #alphacoronaviruses were found. Monitoring rodent populations helps to determine coronavirus occurrence, transmission, and zoonotic potential.

UT article on a new antibody targeting all #coronaviruses :

- Original article begins with ‘Hybrid Immunity’ - TW
- Researchers claim patent...

I suggest reading an "older" paper (ref 2), they make more or less the same discovery and they warn that the S2 region of the spike is subject to strong conformational (shape) changes, in other words, it is very tricky to design a vaccine in this region.

In contrast, none of tested samples was positive for flu A/C/D, bornaviruses, morbilliviruses, lyssaviruses, or pestiviruses.

Scientists create #vaccine with potential to protect against future #coronaviruses

📌 Scientists have created a vaccine that has the potential to protect against a broad range of coronaviruses, including varieties that are not yet even known about.

📌 The experimental shot, which has been tested in mice, marks a change in strategy towards “proactive vaccinology”, where vaccines are designed and readied for manufacture before a potentially pandemic virus emerges.
