A viral video claiming to reveal the ‘hidden side effects’ of COVID-19 vaccines – along with a supposed pharmacy-bought remedy – has been debunked by health experts in Spain.
The clip, which has been widely shared on Facebook, suggests symptoms such as ‘mental fog, insomnia, blood pressure swings, irritability and unexplained fatigue’ are common after vaccination and claims there is a simple solution available in pharmacies.
According to Spain’s General Council of Official Colleges of Pharmacists, the claims in the video do not match known vaccine side effects.
Pharmacist Pablo Caballero, from the organisation’s scientific outreach team, says the most common reactions are mild and short-lived.
These typically include pain or redness at the injection site, along with general symptoms such as headache or fever – effects that usually resolve on their own within a few days.
Spain’s medicines watchdog, the AEMPS, backs this up, stating that side effects are generally ‘mild or moderate’ and linked to the body’s normal immune response.
Rare complications
Experts acknowledge that very rare complications such as myocarditis or pericarditis have been reported in isolated cases, but stress the risk is extremely low and lower than the risk posed by COVID-19 itself.
There is also no scientific evidence to support claims made in the video about widespread inflammation or ‘mitochondrial dysfunction’ caused by vaccines.
No miracle cure
Crucially, the idea that supplements like coenzyme Q10 or omega-3 can ‘reverse’ vaccine side effects is false.
Health authorities insist mild symptoms can be managed with standard painkillers such as paracetamol if needed, but there is no specific treatment required or recommended.
More serious reactions, although very rare, would require proper medical care, not over-the-counter supplements.
Red flags behind the video
The account behind the viral clip presents a woman dressed as a doctor but provides no verifiable credentials, workplace details or medical background.
The videos contain only text overlays, background music and no spoken explanation, with some captions even including spelling mistakes.
Experts warn this fits a familiar pattern of misleading health content designed to appear credible without offering any real evidence.
