A South Korean study by G. Roh et al titled “Comparative immunologic profiling of mRNA and protein-conjugated vaccines: acute inflammatory responses and anti-PEG antibody production” published on 10 June 2025 supports what has been discussed by many doctors since the rollout of the so-called vaccine.

The paper is 16 pages long, with the main text at about 13 pages. The remaining are references.

The study sample is relatively small at 60 individuals in total, 28 males and 32 females, with a mean age of 37.2 ± 9.4 years.

The point of the study is to compare recipients of Pfizer or Moderna COVID-19 mRNA vaccine (test group) to GlaxoSmithKline conjugated meningococcal vaccine (control group).

The test group was comprised of 50 individuals, 22 males and 28 females, with a mean age of about 40 years. The control group was comprised of 10 individuals, 6 males and 4 females, and was significantly younger at a mean age of about 23 years. Blood samples were collected on Day 0, 3 and 7 after vaccination.

Generally, there were more adverse events (AEs) for the test group than the control group, such as headaches, fatigue and muscle aches. Although most of the observations were within normal ranges, there were significant differences between the control and test groups. For example,

…white blood cell (WBC) counts were significantly reduced in the test group on Day 3 compared to those in the control group (p-value = 0.02; p for trend = 0.03). Additionally, although the percentage of monocytes did not show statistical significance, there was a trend toward an increase in the test group on Day 3 compared to the control group (p-value = 0.29; p for trend = 0.28).

For the test group with moderate AEs (Grade 2), the WBC counts were lower than those who had mild AEs (Grade 1) on Day 3.

Also,

…haptoglobin and C-reactive protein (CRP) showed significant elevation on Day 3 in the test group compared to that in the control group (p = 0.02 and <0.01; p for trend <0.0001 and <0.01, respectively).

An increase in haptoglobin levels can be due to the destruction of red blood cells, inflammation or cancer, and CRP is associated with inflammation.

The levels of anti-PEG IgG and IgM antibodies increased on Days 3 and 7 after mRNA vaccine administration, respectively. Additionally, the levels of anti-PEG IgG and IgM antibodies were slightly increased in the Grade 2 group compared with those in the Grade 1 group.

Although higher levels of anti-PEG IgG and IgM antibodies are not always associated with anaphylaxis cases, they are often detected in such cases, which this study seems to corroborate.

There are plenty of other observations but below is one key point that is telling about these mRNA “vaccines”:

The mRNA vaccine recipients exhibited a significant decline in WBC count compared with the protein vaccine recipients. Decreased WBC count after vaccination is not a common or expected outcome; thus, it could be a sign of an unusual reaction or underlying health issue, even though the count did not reach pathological levels. These results suggested that mRNA vaccines may influence the bone marrow, thereby highlighting the need for more detailed toxicity studies.
