![]() ![]() To our knowledge, there is only 1 other report of petechial skin lesions in a SARS-CoV-2–infected patient, initially believed to have dengue fever. No features of thrombotic vasculopathy were present ( Figure 2). Results of real-time reverse transcriptase–polymerase chain reaction from a nasopharyngeal swab were positive for SARS-CoV-2.Ī 5-mm punch biopsy specimen from the left buttock revealed a superficial perivascular lymphocytic infiltrate with abundant red cell extravasation and focal papillary edema, along with focal parakeratosis and isolated dyskeratotic cells. Serologic test results were negative for HIV, hepatitis B virus, hepatitis C virus, and parvovirus B19. The platelet count and coagulation parameters were normal. A complete blood cell count revealed a lymphocyte count of 750/μL (reference range, 1000-4500/μL) (to convert to ×10 9/L, multiply by 0.001), a C-reactive protein level of 1.7 mg/dL (reference range, 0-0.5 mg/L) (to convert to mg/L, multiply by 10), and a D-dimer level of 0.68 μg/mL (reference range, 0-0.5 μg/mL) (to convert to nmol/L, multiply by 5.476). ![]() Posteroanterior and lateral chest radiographs showed ground-glass opacities in both lower pulmonary fields consistent with atypical pneumonia. The exanthem consists of erythematous macules, papules, and petechiae affecting the popliteal fossae (A), buttocks (A and B), and anterior thighs (C).

Fourth dose of COVID vaccine offers only slight boost against Omicron infection. Interim public health considerations for the provision of additional COVID-19 vaccine doses. Risk of infection, hospitalisation, and death up to 9 months after a second dose of COVID-19 vaccine: a retrospective, total population cohort study in Sweden. In conclusion, COVID-19 vaccination is a major risk factor for infections in critically ill patients.ĬOVID-19 Critically ill patients Risk factor Vaccination Vaccine-acquired immunodeficiency syndrome. These include limiting the use of non-steroidal anti-inflammatory drugs, including acetaminophen to maintain deep body temperature, appropriate use of antibiotics, smoking cessation, stress control, and limiting the use of lipid emulsions, including propofol, which may cause perioperative immunosuppression. Several practical measures to prevent a decrease in immunity have been reported. In addition, the date of vaccination should be recorded in the medical record of patients. As a safety measure, further booster vaccinations should be discontinued. These clinical alterations may explain the association reported between COVID-19 vaccination and shingles. The decrease in immunity can be caused by several factors such as N1-methylpseudouridine, the spike protein, lipid nanoparticles, antibody-dependent enhancement, and the original antigenic stimulus. According to European Medicines Agency recommendations, frequent COVID-19 booster shots could adversely affect the immune response and may not be feasible. The study showed that immune function among vaccinated individuals 8 months after the administration of two doses of COVID-19 vaccine was lower than that among the unvaccinated individuals. Recently, The Lancet published a study on the effectiveness of COVID-19 vaccines and the waning of immunity with time. ![]()
