Covid-19 Differences between vaccines
Covid-19 When it's my turn to get vaccinated
Adolfo García-Sastre "Combining vaccines causes confusion"
A new study, published by the
Economic Times
,
suggests that new
coronavirus
variants
could bypass antibodies thanks to
supercells
.
It seems that a highly infectious variant would be able to change human cells, causing them to fuse with two or more nearby cells to give rise to these
super
cells
that are excellent
virus
factories

The data of the coronavirus in Spain
Total figures
: 3,733,600 confirmed coronavirus cases with diagnostic test for active infection;
There have been 80,501 deaths with a positive test as of June 11.
598,947 in Andalusia (9,975 dead)

07.24 Madrid and nightlife meet to study the opening protocols
The Community of Madrid and the nightlife sector are going to meet this Monday to study the protocols and
criteria for the reopening of the
Madrid
nightlife sector
, which proposes a de-escalation in three phases until August with 100% of the activity for return to the "old normality", reports Efe.
The Community of Madrid expects to reopen nightlife
the week of June 21
if the downward trend in coronavirus cases continues, and once protocols and opening criteria are established in the meeting that the Ministry of Health and the Madrid night sector will have on Monday.
07.19 They study the Delta variant and its ability to re-infect
The Delta variant, B.1.617.2 (formerly called the Indian variant) spans the world.
For example, the latest report from the Italian Higher Institute of Health dating from May 18 speaks of a prevalence of 1% and the case of an outbreak in a gym in Milan in which there was at least one case sequenced, that of a toilet.
already vaccinated (with two doses) infected by the Delta variant
.
In Spain, specifically in the Community of Madrid, it has been decided to advance the second dose of the vaccine to those over 60 years of age due to the increase in infections from this variant.
Does the Delta variant weaken the effectiveness of vaccines?
07.16 Vaccination is focused between 40 to 49 years
The Ministry of Health updates this Monday the data of the
coronavirus
pandemic
that is expected to continue to decline thanks to the strong vaccination rate, at a time when all communities have
relaxed restrictions
and
leisure is
slowly
returning
to normal. .
Vaccination now focused on the age group 40-49 years.
07.14 The EMA criticizes the circulation of misinformation about the AstraZeneca vaccine
The European Medicines Agency (EMA) criticized this Sunday that misinformation about AstraZeneca's
coronavirus
vaccine is circulating
, after a senior official of the agency said in an interview with an Italian newspaper that they should opt for other vaccines, reports Efe.
"The misinformation is circulating today. This is the situation: the balance between benefit and risk of AstraZeneca's vaccine against covid is positive and it continues to be authorized for the entire population," the agency said through its Twitter account.
Marco Cavaleri, head of EMA's vaccination strategy, told the Italian newspaper
La Stampa
this weekend
that "it would be preferable to stop using the AstraZeneca vaccine for all age groups when other alternatives are available."
07.06 The variants that are emerging so far have been stopped with vaccination
Adolfo García-Sastre
, from
Burgos
, director of the Global Institute for Health and Emerging Pathogens at Mount Sinai Hospital in New York, is working on a vaccine that has a simple technology, similar to that of the flu vaccine, and that can be produced locally and that facilitates access to countries with fewer resources.
"Combining vaccines causes confusion."

Coronavirus variants can evade antibodies by spreading through supercells
The antibodies that are made after being infected with a virus or after getting vaccinated can be very powerful.
A
virus
generally spreads within a body by entering a cell and using it as a factory to create copies of itself, which then explode and find new cells to infect.
Antibodies work by binding to the virus and this can prevent it from sticking to and entering cells.
But what if a virus does not need to leave the cell to spread to neighboring cells?
Can antibodies be effective against it?
According to a new study echoed by the
Economic Times
new variants of the
coronavirus
could get around that barrier thanks to
supercells
. This highly infectious coronavirus can change human cells, causing them to fuse with two or more nearby cells. These
supercells
, with large fused cell bodies, are excellent virus factories.
Supercells, known as
syncytia
, share multiple nuclei (the part of the cell that contains genetic material) and abundant cytoplasm (the jelly-like substance that surrounds the nucleus). Having more of these components in a giant cell helps the virus replicate more efficiently. And by fusing cells,
SARS-CoV-2
increases its resources without being exposed to the neutralizing antibodies that spill out of our cells.
Alex Sigal's study tested two coronavirus variants (alpha and beta) for their ability to transmit from cell to cell and investigated whether this mode of transmission was sensitive to
antibody
neutralization
.
The alpha variant (first identified in the UK) is sensitive to antibodies and the beta variant (first identified in South Africa) is less sensitive to these antibodies.
