Pneumococcal Vaccine Uptake Lagging After Hospitalization: Hong Kong Study
A recent study conducted in Hong Kong has revealed alarmingly low rates of pneumococcal vaccine uptake among adults following hospitalization for pneumococcal disease. The research,published in *Vaccines*,underscores significant missed opportunities for secondary prevention and highlights the urgent need for improved vaccination strategies.
low Vaccination Rates Persist Post-Discharge
The study, which examined data from 2015 to 2024, found that a significant proportion of patients eligible for pneumococcal vaccination did not receive it, even after being hospitalized for a pneumococcal infection. This is despite the fact that pneumococcal disease poses a significant global health burden,particularly for young children and older adults,according to the World Health Organization WHO.
Researchers analyzed electronic health records to assess vaccination rates before, during, and after hospitalization, also considering the impact of the COVID-19 pandemic. The analysis included the 13-valent PCV (PCV13),15-valent PCV (PCV15),and 23-valent polysaccharide pneumococcal vaccine (23vPPV).
Did You Know? …
The CDC recommends pneumococcal vaccination for all adults 65 years or older and for younger adults with certain risk conditions.
key Findings on Vaccine Uptake
Of the 5,517 patients included in the study, 4,469 (81%) were eligible for pneumococcal vaccination. However, only 16.8% of all patients and 20.5% of eligible patients had received any dose of a pneumococcal vaccine before developing the infection. After discharge, the uptake rate remained low, with only a slight increase from 8.1% to 9.8% in full vaccination uptake.
The study also revealed that the vast majority (93.8%) of patients had previously received medical care in a public hospital, and 92.5% had visited outpatient clinics, indicating numerous missed opportunities for vaccination during routine healthcare visits.
Pro Tip: …
Healthcare providers should proactively assess patients’ vaccination status during every visit and offer pneumococcal vaccines to those who are eligible.
Impact of COVID-19 Pandemic
The COVID-19 pandemic further exacerbated the issue, with vaccination rates declining during the pandemic period (January 2020 to December 2022). Post-discharge vaccination rates ranged from 2.4% to 5.7% in the baseline period, 0.5% to 2.1% during the COVID-19 period, and 0.8% to 4.5% in the post-COVID-19 period within the initial 12 months.
This decline can be attributed to disruptions in healthcare services, a shift in focus towards COVID-19 vaccination efforts, and potential hesitancy among patients to seek medical care during the pandemic.
Missed Opportunities and Future Strategies
The study authors emphasized that their research is the first to specifically explore missed opportunities for pneumococcal vaccinations post-recovery from pneumococcal disease. They concluded that the findings are crucial for guiding the selection of pneumococcal conjugate vaccine formulations and improving vaccination strategies.
To address this issue, healthcare systems need to implement more thorough interventions to increase vaccine uptake. This includes:
- Improving awareness among healthcare providers about the importance of pneumococcal vaccination.
- Implementing reminder systems to ensure that eligible patients are offered the vaccine.
- Addressing logistical barriers to vaccination, such as making vaccines more accessible in outpatient clinics and hospitals.
| Time Period | vaccination Rate before Infection | Vaccination Rate After Discharge |
|---|---|---|
| Baseline (2015-2019) | 16.8% | 2.4% – 5.7% (within 12 months) |
| COVID-19 Pandemic (2020-2022) | Data Not Specified | 0.5% – 2.1% (within 12 months) |
| Post-Pandemic (2023-2024) | Data Not Specified | 0.8% – 4.5% (within 12 months) |

Evergreen Insights: Understanding pneumococcal Disease and Vaccination
Pneumococcal disease is an infection caused by the bacterium *Streptococcus pneumoniae*. it can lead to serious illnesses such as pneumonia, bacteremia (bloodstream infection), and meningitis (infection of the brain and spinal cord). Vaccination is a safe and effective way to prevent pneumococcal disease.
There are two main types of pneumococcal vaccines: pneumococcal conjugate vaccines (PCV13 and PCV15) and the pneumococcal polysaccharide vaccine (PPSV23). PCV13 and PCV15 protect against 13 and 15 types of pneumococcal bacteria, respectively, while PPSV23 protects against 23 types. The Centers for Disease Control and Prevention CDC provides detailed recommendations on who should receive each type of vaccine.
historically,pneumococcal disease was a leading cause of childhood mortality.However,the introduction of pneumococcal conjugate vaccines has substantially reduced the incidence of invasive pneumococcal disease in children. Despite this progress, pneumococcal disease remains a significant threat to older adults and individuals with certain medical conditions.
Frequently Asked Questions About Pneumococcal Vaccines
- Who should get a pneumococcal vaccine?
- the CDC recommends pneumococcal vaccination for all adults 65 years or older and for younger adults and children with certain medical conditions that increase their risk of pneumococcal disease.
- Are there any side effects from the pneumococcal vaccine?
- Most people experience only mild side effects from the pneumococcal vaccine, such as soreness, redness, or swelling at the injection site. Serious side effects are rare.
- How effective is the pneumococcal vaccine?
- The pneumococcal vaccine is highly effective at preventing serious pneumococcal infections. Studies have shown that it can reduce the risk of invasive pneumococcal disease by up to 75%.
- How often do I need to get a pneumococcal vaccine?
- Most adults only need one or two doses of the pneumococcal vaccine in their lifetime. However, individuals with certain medical conditions may need additional doses.
- Can I get the pneumococcal vaccine at the same time as other vaccines?
- Yes,the pneumococcal vaccine can be given at the same time as other vaccines,such as the flu vaccine or the COVID-19 vaccine.
