COVID herd immunity – only with vaccines and other public health measures

coronavirus herd immunity

Let’s talk about COVID-19 herd immunity, which is something that is being tossed about by everyone, including the British Prime Minister. I guess until the point that Boris Johnson contracted COVID-19

Herd immunity is one of those terms in public health that is misunderstood and misused by people who are on all sides of science from vaccine deniers to vaccine advocates.

But there’s one thing we should remind ourselves – coronavirus herd immunity is no panacea, and it probably won’t happen without a COVID-19 vaccine, which is probably years away. Furthermore, pandemics like COVID-19 are almost impossible to predict – which makes it even more difficult to determine if we can even have herd immunity for this disease.

Genetics cause autism in new study – once again, it’s not about vaccines

Let’s start right at the top – a new, powerful study has shown that mostly genetics cause autism. Despite the fear, uncertainty, and doubt from the anti-vaccine religion, we have overwhelming scientific evidence that vaccines are not linked to autism spectrum disorder (ASD). This is settled science

Almost all legitimate science researchers who focused on autism never bought into the vaccines link. Not only was there no evidence of this imaginary link (thanks to the cunning fraud Andrew Wakefield), when scientists went looking for a possible link, they never found one. 

However, investigators have been searching for legitimate underlying etiologies for ASD – the hypothesis that genetics cause autism has been the center of research for years. 

So let’s look at this study in detail so that we all have more evidence to shut down the vaccines and autism tropes. Well, at least we can try, since the pseudoscience that permeates the anti-vaccine world is resistant to scientific facts (see Del Bigtree).  Continue reading “Genetics cause autism in new study – once again, it’s not about vaccines”

HPV vaccine safety – another massive scientific study (UPDATED)

HPV vaccine safety

In a 2013 study of over 1 million girls, the overall HPV vaccine safety for teenage girls was reaffirmed. There appear to be no links between serious adverse events and the HPV vaccines. This is in line with numerous other large size epidemiological studies of HPV vaccines.

Let’s take a look at the HPV vaccine safety that is supported by this trial.

HPV–early vaccination maximizes effectiveness


HPV protesters in Texas.

Human papillomavirus (HPV) is a virus from the papillomavirus family that is capable of infecting humans. Like all papillomaviruses, HPVs establish productive infections only in keratinocytes of the skin or mucous membranes, making it easily transmitted sexually or through other intimate contact. While the majority of the known types of HPV cause no symptoms in most people, some types can cause warts (verrucae). HPV types 16 and 18 cause approximately 70% of cervical cancers, and cause most HPV-induced anal, vulvar, vaginal, and penile cancers. The HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), is marketed by Merck. The vaccine prevents the transmission of certain types of HPV, specifically types 6, 11, 16 and 18

Although the safety of HPV vaccine has been thoroughly vetted for safety in studies with large cohorts, the long time period (up to decades) from infection to a diagnosis of an HPV-related cancer has left questions about how to maximize effectiveness of the vaccine which required further research.  Continue reading “HPV–early vaccination maximizes effectiveness”

Study clears vaccines as cause of Swedish celiac disease increase

A recently published study in Pediatrics, Early Vaccinations Are Not Risk Factors for Celiac Disease by A Myléus et al., concludes that “early vaccinations within the national Swedish program were not associated with celiac disease risk, nor could changes in the program explain the Swedish epidemic.” As background, between 1984 and 1996, the incidence of celiac disease in Swedish children under the age of two increased by four times. The increase ended just as abruptly. The cause of the increase and sudden end has been a mystery to researchers ever since.

Celiac disease, an autoimmune disorder that causes an abnormal response to gluten digestion, results from certain gene variants, but the disorder seems to be expressed as a result of unknown environmental factors. One of the factors that has been blamed in the past has been vaccines and were considered a culprit in the case of the Swedish children. However, no studies have ever shown a causation between vaccinations and expression of celiac disease, and this study dismisses any link in this particular situation.

Myléus et al. actually found that the introduction of pertussis, or whooping cough, vaccines corresponded with a decline in the incidence of celiac disease.  They continue to research the causes of the spike in celiac disease, since it might help with prevention of the expression of the underlying gene variants. For example, Myléus et al. believe that high wheat formulas used in Sweden at the time may hold the answer to the question. 

But at this time, the anti-vaccine lunacy can quit blaming celiac disease on vaccines.
