Why vaccination isn't reaching Africa and what can be done to change it

"Equity in the distribution of vaccines is not a matter of charity; it benefits all countries," said Tedros Adhanom, director of the WHO. However, his data speak of a very unequal distribution: more than 80 % of the vaccines have gone to G20 countries, while poor countries, mostly African, have received only 0.6 %. Three Spanish experts analyze what went wrong.

What we know about the effectiveness of the vaccines against Omicron

The new B.1.1.529 variant, dubbed Omicron, has spread across the globe, with new countries announcing its detection with each passing day. While questions such as whether it is more transmissible are being investigated, the biggest question surrounds its relationship with vaccines - will they cease to be effective, and will this variant escape our immune systems? Several experts answer.

Rapid reaction to the first case of the Omicron variant detected in Spain

The discovery of the Omicron variant has led to the cancellation of flights to several African countries, while many countries are beginning to detect cases among travellers from countries such as South Africa, but also Nigeria and Egypt. Spain has just announced the first detected case of Omicron, which corresponds to a traveller who had visited South Africa. What measures should be taken to stop the spread of this variant? Is it even possible?

Expert reaction on the new variant B.1.1.529 detected in South Africa

A new variant of the coronavirus causing COVID-19 has been identified in South Africa, with numerous mutations present in other variants, including Delta. Variant B.1.1.529, as it is now called, appears to be spreading rapidly in South Africa. Attached is the rapid reaction of three Spanish researchers with expertise in genomic surveillance.

Why masks and distance are important just now that we have been vaccinated

The message that we must continue to protect ourselves with masks, distance, ventilation and hand washing has been repeated since the beginning of vaccination, but in the midst of the pandemic in Europe it is even more important. Several experts warn that the high vaccination coverage in Spain will mitigate the new wave but will not eliminate it: although vaccines prevent serious disease, they are not an insurmountable shield and must be complemented with behavioral measures.

Are punitive measures on unvaccinated people against covid effective?

European countries are implementing anti-covid strategies in the unvaccinated population. Austria will make vaccination mandatory after extending its confinement targeting the unvaccinated to the entire population. In Germany, the unimmunized have restricted access to restaurants and hotels, and must show a negative test on public transport. Slovakia has also imposed restrictions on those who have chosen not to be vaccinated. Sweden will introduce a covid passport at events of more than 100 people. What is the effect of these policies?

Reaction to the study analysing the generation of specific memory T-cells after vaccination with Pfizer

A study has monitored T-lymphocyte responses to the SARS-CoV-2 spicule in 71 healthy donors who received two doses of Pfizer's vaccine. After up to six months' follow-up, the researchers found that specific memory cells were generated and maintained and persisted for at least six months.
