From "vaccines cause infections" to "it is not necessary to be vaccinated in summer because the virus dies".
Countless false news about Covid vaccines circulate on the Internet.
This vademecum, edited by the Vaccine Group of the
Italian
Higher Institute of Health
, responds to the most widespread hoaxes.
Are the short-term and long-term effects of vaccines unknown?
We hear that "the short-term and long-term effects are unknown" and that "the vaccines were produced too quickly and the only information comes from the companies" - but is it true?
The pharmacovigilance system for
coronavirus
vaccines
is the same as for all other previously approved drugs and vaccines.
Following the results of studies carried out with tens of thousands of individuals of different ages, which have also been carried out in this case, the reports of national and international regulatory agencies of possible adverse events temporally correlated with vaccination are collected.
If adverse events not reported during the authorization studies are highlighted, if a causal relationship with vaccination is suspected or demonstrated after a thorough investigation, they are added to the list of adverse reactions and listed in the information sheets. of the different vaccines.
Are Covid Vaccines Experimental?
The licensed
coronavirus
vaccines
have completed all the steps necessary to obtain marketing authorization, without skipping any of them.
For these vaccines the development process has experienced an unprecedented acceleration worldwide, but at the time of their authorization by the
European Medicines Agency
(
EMA
)
the same steps in the procedure envisaged for any vaccine on the market had been completed.
The vaccines that are currently used in the vaccination campaign in Europe (
Pfizer
,
AstraZeneca
,
Moderna
and
Janssen
) are not, therefore, experimental, but safe drugs that have only been marketed after completing the process that proves their quality, safety and effectiveness.
Do vaccines cause infection?
Vaccines currently in use in the EU use
messenger RNA
technology
(
Pfizer
and
Moderna
) and viral vector technology (
AstraZeneca
and
Janssen
).
In both cases, "instructions" are introduced into the body to produce fragments of the protein that the virus uses to "latch onto" the cell.
Therefore,
live and infectious
SARS-CoV-2
is not used
.
A possible
Covid-19
disease
after vaccination can only be caused by a natural infection of the virus contracted independently of the vaccine.
Are vaccinated people contagious?
This is possible because, as with all existing vaccines, the efficacy, although very high, is not 100%, which is why so-called "vaccination failures" can occur.
Furthermore, even a patient who responds to the vaccine can be considered immunized only after at least one week from the completion of the full regimen.
A high level of population coverage in the population minimizes the risk of transmission between individuals susceptible to infection.
Data from countries with an advanced vaccination campaign show that the vaccine protects more than 9 out of 10 vaccinated people against the worst consequences of the disease, from hospitalization to death.
Vaccination also reduces the ability of those vaccinated to infect.
Are post-vaccine side effects and deaths hidden?
Drug surveillance data is public.
The
EMA
periodically publishes the report of notifications of suspected adverse events, and so does the
Spanish Medicines Agency
with its pharmacovigilance reports.
Does the vaccine cause infertility and miscarriages?
There is currently no scientific evidence of a negative effect of vaccines on male or female fertility.
Regarding the administration of the vaccine during pregnancy, the first observations, especially from the US data where there are thousands of women immunized during pregnancy, did not reveal an increased risk of adverse effects for mothers and newborns.
Does the vaccine change our DNA?
Covid-19
vaccines
do
not change and do not interact in any way with
DNA
.
Both messenger RNA and viral vector vaccines provide instructions to our cells to activate an immune response that protects us against the
coronavirus
.
Does the vaccine cause thrombosis and myocarditis?
All medicines and vaccines can have side effects.
Regulatory agencies report these two pathologies, which are also among those caused by infection, as rare adverse effects of vaccination.
Precisely because of their extreme rarity, these effects still leave the benefit-risk ratio in favor of the former, as pointed out by all international regulatory bodies.
People under 20 years old do not die from Covid, is it useless to vaccinate them?
"From 19/20 years and under it is impossible for a healthy person to die from Covid, and even to manifest serious symptoms."
Again, a
hoax
.
Although the risk of developing a symptomatic infection is lower in younger age groups than in adults, it also happens.
From the start of the pandemic to July 17, for example, there have been 28 deaths in the 0-20 age group in Italy.
In any case, the purpose of vaccination even in the youngest age groups is also to limit the circulation of the virus at the population level and thus allow an escape from the pandemic, as well as protect the most vulnerable.
The more we vaccinate, the more new variants come out?
Variants arise because the virus, when replicating, tends to develop new mutations.
Vaccines, by reducing circulation, therefore limit the possibility of mutation of the virus.
The variants in circulation at this time, including the
Delta
, were first observed last December, when vaccination campaigns had still started in very few countries.
In summer the virus disappears: what is the use of getting vaccinated or wearing a mask?
The transmission of the virus is easier in closed environments, but it also circulates outdoors, so it is necessary to adopt the appropriate measures.
