The Indian variants : Kappa, Delta and Delta+

We are still witnessing the emergence of variants. The more the virus is transmitted, the greater the risk. In general, these variants possess a particular advantage: greater transmissibility or some capacity for evasion of immune responses. Variants that have already appeared include the Beta (South African), Gamma (Brazilian) and Alpha (UK): the latter became the […]


Simultaneous vaccine against COVID-19 and flu

Vaccination against SARS-CoV-2 has enabled the prevention of numerous cases of COVID-19, and numerous deaths. But this process of mass vaccination takes its toll on health systems since it involves many health professionals. In several countries, vaccination against COVID-19 is given at the same time as vaccination against winter flu. This latter is important since […]


Interfering viruses: a new therapy against COVID-19

In general, evolution enables pathogens, whether viral or bacterial, to acquire resistance to antimicrobials. SARS-CoV-2 is no exception to this principle. Emerging variants, such as the Alpha (UK), Beta (South African) or Delta (Indian) variants, seem to be more transmissible or more resistant to antibodies generated by previous infection or by vaccination. In order to […]


How does SARS-CoV-2 attack the olfactory system?

Anosmia or loss of smell is a common symptom of COVID-19. The mechanism of this phenomenom is poorly understood but some studies suggest that the olfactory nerves may serve as a pathway for SARS-CoV-2 to enter the brain. Studies on the olfactory mucosa and human olfactory bulbs have not advanced very far, since it is […]


Are NK cells effective against SARS-CoV-2?

Innate, or non-specific, immunity is one of the organism’s first lines of defence against pathogens. NK (Natural Killer) cells are one element of this immunity. These cells are lymphocytes which, unlike B and T lymphocytes in adaptive immunity, do not need to have had previous contact with the pathogen in order to become rapidly active […]


Moderna and Pfizer-Biontech vaccines against the Delta variant in Qatar

In Qatar, the SARS-CoV-2 Alpha variant and then the Beta variant, were at the origin of two major epidemic waves at the beginning of 2021. It was later, in March, that the Delta variant was detected. It then spread throughout the country and was responsible for 43% of infections up to September. However, the vaccination […]
