Article Synopsis
  • The COVID-19 pandemic has had severe health and economic impacts globally, with vaccination being crucial for control, especially in regions with high rates of helminth infections, which could affect vaccine responses.
  • A study in Uganda surveyed 450 individuals to assess helminth prevalence and COVID-19 vaccine responses; results showed high infection rates of schistosomiasis (36.4%) and hookworms (36.9%), with 93.14% vaccination coverage among a smaller group interviewed.
  • Despite widespread vaccination, a significant portion of those vaccinated had low anti-S1 IgG antibody levels, indicating that helminth infections might reduce vaccine efficacy among individuals with moderate to heavy infections.

We compare critical quantum sensing to passive quantum strategies to perform frequency estimation, in the case of single-mode quadratic Hamiltonians. We show that, while in the unitary case both strategies achieve precision scaling quadratic with the number of photons, in the presence of dissipation this is true only for critical strategies. We also establish that working at the exceptional point or beyond threshold provides suboptimal performance.
