Research Sheds Light on Side Effects of COVID-19 Vaccination

By Dr Frank Yap, M.D. -

Shortly following their COVID-19 vaccinations, individuals in Denmark reported mild side effects like general discomfort, elevated body temperature, and tiredness. Severe adverse reactions like facial paralysis and allergic responses are rare. Additionally, 30% of menstruating women reported alterations in their menstrual cycles.

Aarhus University has recently published two studies examining the side effects of COVID-19 vaccines. Both studies are based on the Danish BiCoVac cohort, which makes it possible to carry out studies based on a large group of the Danish population. One of the studies examined the acute side effects of Covid-19 vaccination.

The most frequently reported side effects after the first small prick on the shoulder are redness and pain at the injection site, which 20% of people experience. After the second and third jabs, fatigue is the most reported side effect – reported by 22% and 14% of people, respectively.

The study has been published in the journal Vaccine. The study found that common side effects such as malaise, fever, and fatigue are among the most frequently reported in Denmark after Covid-19 vaccination. More serious side effects such as facial paralysis and allergic reactions are not as common.



“Women, people between the ages of 25-35, and people who had Covid-19 prior to being vaccinated reported experiencing side effects more frequently than men, the elderly, and people who had not previously had Covid-19,” says Kristoffer Torp Hansen, first author of the study and research assistant at the Department of Public Health.

The results also show that the acutely occurring side effects differ depending on which vaccine is administered.

People vaccinated with the AstraZeneca vaccine reported more side effects after the first dose than people vaccinated with the other vaccines.

People who received the Moderna vaccine reported more side effects after the second and third doses compared to people who received the vaccine from Pfizer-BioNTech.

Several factors play a role in the reporting of menstrual changes

The second study showed that 30% of menstruating women reported changes in their menstrual cycle after being vaccinated against Covid-19.

The researchers examined which factors could potentially play a role in those changes and discovered that commonly known causes of menstrual changes, such as stress, age, and smoking, had a correlation with the reported cycle changes after Covid-19 vaccination.

“We also found that women who had been concerned about the Covid-19 vaccine, who had had a severe Covid-19 infection or who reported experiencing several reactions to the vaccine were more likely to report menstrual changes after vaccination,” says Christina Bisgaard Jensen, PhD student at the Department of Public Health. She is the first author of the study, which has just been published in the scientific journal Human Reproduction.

“Changes in the menstrual cycle are not uncommon, and we cannot rule out that, for some people, the reported menstrual changes occurred randomly in temporal relation to the vaccination,” says Christina Bisgaard Jensen, who further explains that the study cannot be used to identify a direct correlation between Covid1-9 vaccination and the reported menstrual changes.

“Further studies are needed to establish causal relationships and the clinical significance of self-reported menstrual changes,” she says.

FLCCC I-Recover Protocol: Post Vaccine Treatment Protocol (2024)

By Dr Frank Yap, M.D. -
Image
Over the last three years, the COVID-19 pandemic has transformed almost every aspect of our lives before we've had time to stop and question it. Although no official definition exists for post-COVID-vaccine syndrome, a temporal correlation between a patient receiving a COVID-19 vaccine and beginning or worsening of clinical manifestations is sufficient to diagnose as a COVID-19 vaccine-induced injury, when the symptoms are unexplained by other concurrent causes. Dr. Paul Marik and Dr. Pierre Kory are pleased to introduce the I-RECOVER: Post-Vaccine Treatment protocol, designed to help people who have experienced adverse symptoms after a COVID vaccine. Kory and Marik are both part of the FLCCC, which was founded in 2020 to share early treatment protocols for COVID-19. Kory is an ICU specialist, triple board certified in internal medicine, critical care and pulmonary medicine. He now runs a private tele-health practice specializing in the treatment

Front Line Doctors Ivermectin Protocol for Prevention and Treatment of COVID-19 (2024)

By Dr Frank Yap, M.D. -

The Front Line COVID-19 Critical Care (FLCCC) Alliance was initially formed as a working group during the early COVID-19 pandemic days in response to multiple early reports of COVID patients with an inexplicably high need for prolonged mechanical ventilation and an excessive death rate.  Based on rapidly emerging clinical trials evidence, the FLCCC team has developed the   I-MASK+ protocol   ( is now divided into I-Prevent and I-Care protocols ) for prophylaxis and at home treatment of early stage COVID-19. Quercetin, zinc and a number of nutrients and drugs are part of this protocol, not only for critical care but also for prophylaxis and mild disease being treated at home. This article, we will dive deeper to provide the scientific background, related references and rationale of the FLCCC protocols.

Quercetin and Zinc: Zelenko Treatment Protocol

By Dr Frank Yap, M.D. -

As of July 2024, more than 35 studies on the topic of zinc and COVID-19  ( c19zinc.com )  (constantly updated) and more than 10 studies on quercetin and COVID-19 have been published  ( c19quercetin.com ).  Dr. Zelenko’s main hypothesis based on the data showing that early intervention and treatment of high-risk patients with COVID-19 results in significantly few hospitalizations and deaths. This treatment regimen involving zinc, low-dose hydroxychloroquine, and azithromycin (published in the International Journal of Antimicrobial Agents ) is also apparently known as, “The Zelenko Protocol.” Quercetin and Zinc The Zelenko Covid-19 Protocols was developed by Dr Vladimir Zelenko. The protocol has as its centerpiece, but not exclusive piece, the combined use of  Hydroxychloroquine  (HCQ) and Zinc as a means by which a person can both help to prevent or mitigate the contraction of COVID-19, or can actually treat the disease once it has been diagnosed.  Quercetin is a natural antihistamine a
