Les mesures de prévention de la Covid empêchent le système immunitaire des enfants de se développer correctement. Ils pourraient souffrir davantage d’allergies, d’asthme et de maladies auto-immunes.

COVID-19 prevention measures are at odds with guidelines for healthy development of children’s immune systems. The result may be a cluster of youth with more allergies, asthma and autoimmune disease.
The arrival of COVID-19 vaccines has raised hope for an end to the pandemic. Hopefully that’s true, but there are variables. Here are some factors that could affect the success of the vaccine rollout.
In the disturbing scenario of human-to-mink-to-human COVID-19 transmission, the virus may mutate in mink prior to re-infecting people. That possibility makes vaccine design even more crucial.
Notre exposition à un agent pathogène, que ce soit naturellement ou par la vaccination, peut affecter la manière dont notre système immunitaire réagira à l’avenir à des agents pathogènes similaires.
Our first exposure to a pathogen, either naturally or via vaccination, can affect how our immune system responds in the future to the same or similar pathogens.
Immunosenescence — the decline of immune system function with age — means that vaccines are not as effective in older adults, the demographic most susceptible to many diseases, including COVID-19.
It usually takes 10 years for a new vaccine to complete clinical trials, but we’ve been promised a COVID-19 vaccine in 12 to 18 months. Even if such fast-tracked development is possible, is it wise?
Immunity to COVID-19 may be complicated. Here are the promises and pitfalls of antibody tests.
