“Pioneer study” confirms Covid vaccines alter women’s periods

Spanish study adds to research coming out of the United States

A “pioneer study” by researchers at the University of Granada in Spain has confirmed that the Covid vaccines “provoke alterations in the menstrual cycle”.

This is a reality that was flagged early on in the mass vaccine roll-out but dismissed as ‘fake news’ powered by conspiracy theorists.

As reports giving details of the Spanish project EVA study admit “no clinical trials on the effects the vaccines might have on menstrual cycles were conducted” before they were given emergency use authorisation for world-wide rollouts.

The Spanish study involved 23,000 women of which 78% reported changes to their habitual cycles.

Most prevalent pre-menstrual symptoms were increases in tiredness – 43%; swelling – 37%; irritability – 29%; feelings of sadness -28%; while menstruation itself found 43% of women suffering greater bleeding, 41% greater levels of pain, 34.5% reporting longer periods of bleeding and 38% saying their periods arrived later than usual.

The vaccines themselves have gone on to demonstrate that they do not stop transmission of Covid-19, nor ensure that people inoculated are not themselves infected (some still becoming seriously ill, and some even dying). 

With studies like EVA getting exposure, elsewhere the World Health Organisation is still warning of the dangers of Covid-19 and the challenges expected in the autumn. It has just released a global vaccine strategy update “to reach the unprotected”.

In Portugal, Covid figures have been steadily reducing (in terms of cases, deaths, hospitalisations and serious illness), albeit elderly patients have continued to die, in spite of vaccine coverage. 

The latest DGS update – for the week of July 12-18) registered 12,898 FEWER infections that the previous week (a total of 35,945 new cases) and 28 FEWER deaths (the virus caused 107 deaths in the seven day period: 74 in victims over the age of 80; 24 in 70-79 year olds; 4 in people aged 60-69; 4 in people aged 50-59, and one death in a victim aged between 40-49). No information on clinical history or underlying conditions is ever made public – albeit the DGS report acknowledges that 93% of the population has “complete immunity” (whatever that actually means).

Meantime, in America, researchers have also been investigating changes to menstrual cycles, concluding that they “may be far more common than previously known“.

According to the US study, breakthrough bleeding has even been reported in ‘non-menstruating people’ (ie women who have passed through the menopause and even those on ‘certain long-term contraceptives’).

The bottom line of the US study is that these changes are “temporary”. A ‘difference’ flagged in the Spanish study (which did not refer to the temporary nature of the alterations) is that they seem to affect smokers more than non-smokers.

The Spanish study has been described today in the Portuguese press as “pioneer” essentially because it is the first study into menstrual changes within the Spanish population, albeit researchers have said that “more studies are needed to described the physiological mechanisms that explain these alterations“.
