Chapter 1: Vaccination Insights from Portugal

Recent analysis indicates that between 95% and 97% of healthcare workers at CHUSJ in Portugal developed antibodies to the Coronavirus just 15 days after receiving their vaccinations.

The discussion surrounding the COVID-19 vaccine has significantly heightened awareness about the necessity of vaccinations. I recently explored this topic from a personal standpoint in my article titled "How an Old Army Vaccine May Have Saved My Life." Additionally, I authored a piece named "I’m Allergic to Penicillin — Should I Get the COVID Vaccine?" which was published in BeingWell and resonated well with my audience.

The public's interest in these articles likely stems from the ongoing debate regarding the choice to vaccinate. It is important to clarify that I hold no affiliation with any particular movement; I am neither a proponent nor an opponent of vaccinations. My writings stem solely from my personal experiences and reflect my individual opinions, values, and beliefs.

I strive to express my thoughts without passing judgment on others' viewpoints. My aim is to present information based on factual and scientific understanding as best as I can.

According to a study published in The Lancet, herd immunity is generally established when 75% to 90% of the population becomes immune, either through natural infection or vaccination. Therefore, if a significant segment of the global population chooses to avoid vaccination and allows the virus to spread unchecked, the time required to reach herd immunity will increase dramatically.

I have experienced both sides of this debate. Not long ago, I was skeptical about the new mRNA vaccines. However, my perspective shifted dramatically after the phase 3 trial results were released, demonstrating that several new vaccines achieved effectiveness rates of over 70%, with some exceeding 90%.

In 2021, news of the vaccine's positive effects on healthcare workers has brought relief, as the outcomes have surpassed our initial expectations. Portugal's official news agency, Lusa, reported that 95% to 97% of healthcare professionals vaccinated against COVID-19 at São João Hospital and Medical Center (CHUSJ) in Porto showed antibodies indicative of immunity just 15 days post-vaccination.

Among the 2,125 doctors, nurses, operational assistants, and diagnostic and therapeutic technicians who were among the first to receive the vaccine on December 27, a small group underwent serological testing to assess vaccine-induced immunity.

Dr. Tiago Guimarães, the Director of Clinical Pathology at CHUSJ, stated to Lusa that the results were as anticipated and reaffirmed the effectiveness of the Pfizer vaccine: “We are not reporting anything unexpected, but it is encouraging to see that it has worked and reinforces the value of vaccination. The vaccination process should proceed as swiftly as possible.”

Dr. Guimarães highlighted that the tests conducted differed from typical antibody tests; they specifically measure the antibodies generated by the vaccine rather than those from a natural infection.

Three rounds of testing were performed—immediately after vaccination, a week later, and again after 15 days. The findings revealed that “95 to 97% of participants were already generating antibodies, indicating presumed immunity.”

“Almost all individuals produced antibodies from the vaccine by 15 days. In the second round, 10 to 15% had already developed antibodies induced by the vaccine. The goal is to determine the timeline for antibody production,” he explained.

He emphasized that these results should inspire “confidence” among those who may still be uncertain about getting vaccinated.

Despite some reports of vaccinated individuals contracting the virus shortly after, Dr. Guimarães noted that these cases were likely due to exposure either before vaccination or shortly thereafter, as antibody production does not occur instantly.

According to Lusa, the COVID-19 pandemic has resulted in at least 1,979,596 deaths worldwide from over 92.3 million cases, while Portugal has experienced 8,384 fatalities from 517,806 confirmed infections.
