Abstract

Immunization with live measles virus vaccine produces transient depression of delayed-type hypersensitivity (DTH) skin test responses and mitogen-induced lymphoproliferation irrespective of the serostatus of the recipient of the vaccine. To investigate this immune suppression further we studied peripheral blood mononuclear cells (PBMC) from adults before (N = 17) and at various times after (N = 34) immunization with measles virus vaccine. PHA-induced lymphoproliferation was decreased after vaccine and this was partly reversed by supplementation with rIL-2. There was no change in the proportion of PBMC that were CD4⁺ T cells, CD8⁺ T cells, NK cells, or B cells as analyzed by flow cytometry. Supernatant fluids were collected from PBMC after 72 hr in culture. Analysis for cytokines after vaccination showed spontaneous production of high levels of IL-4 (vaccinees 99 ± 23; controls 5.6 ± 5.6 ng/ml, P = 0.031) and TNFα (vaccinees 140 ± 45; controls 42 ± 14 pg/ml, P = 0.072) accompanied by low levels of IFN-γ (vaccinees 1.3 ± 0.6; controls 14.3 ± 10.1 U/ml), IL-1α (vaccinees 111 ± 22; controls 442 ± 107 pg/ml, P = 0.0001), and PGE₂ (vaccinees 75 ± 39; controls 300 ± 72 pg/ml, P = 0.048). Increased amounts of IL-4 were also produced after stimulation with PHA (vaccinees 140 ± 25; controls 40 ± 40 ng/ml, P = 0.013) while levels of IFN-γ and soluble IL-2 receptor were similar to controls and levels of IL-1α (vaccinees 443 ± 67; controls 792 ± 118 pg/ml, P = 0.026) remained low. Addition of rIL-2 had little effect on these cytokine levels. These data suggest that Th2 cells producing IL-4 are preferentially activated by measles vaccine and may contribute to the immunologic abnormalities associated with immunization for measles and possibly other viral infections.

Expression kinetics of ISG15, IRF3, IFNγ, IL10, IL2 and IL4 genes vis-a-vis virus shedding, tissue tropism and antibody dynamics in PPRV vaccinated, challenged, infected sheep and goats

The PPRV unvaccinated infected animals exhibited a better Th1 response (increased IFN gamma) than the vaccinated animals of both the species. It is established that generation of a Th1 response is less efficient after vaccination than natural infection [40] [39]. The higher expression of IL10 at 9 dpi in both the species indicated immunosuppression at peak viral load.
Here, we studied the in vivo expression of Th1 (IL2 and IFN gamma) and Th2 (IL4 and IL10) - cytokines and antiviral molecules - IRF3 and ISG15 in peripheral blood mononuclear cells in relation to antigen and antibody dynamics under Peste des petits ruminants virus (PPRV) vaccination, infection and challenge in both sheep and goats. Vaccinated goats were seropositive by 9 days post vaccination (dpv) while in sheep idiosyncratic response was observed between 9 and 14 dpv for different animals. Expression of PPRV N gene was not detected in PBMCs of vaccinated and vaccinated challenged groups of both species, but was detected in unvaccinated infected PBMCs at 9 and 14 days post infection. The higher viral load at 9 dpi coincided with the peak clinical signs of the disease. The peak in viral replication at 9 dpi correlated with significant expression of antiviral molecules IRF3, ISG15 and IFN gamma in both the species. With the progression of disease, the decrease in N gene expression also correlated with the decrease in expression of IRF3, ISG15 and IFN gamma. In the unvaccinated infected animals ISG15, IRF3, IFN gamma and IL10 expression was higher than vaccinated animals. The IFN gamma expression predominated over IL4 in both vaccinated and infected animals with the infected exhibiting a stronger Th1 response. The persistent upregulation of this antiviral molecular signature - ISG15 and IRF3 even after 2 weeks post vaccination, presumably reflects the ongoing stimulation of innate immune cells.

Unravelling the nature of non-specific effects of vaccines—A challenge for innate immunologists

No studies have examined possible epigenetic reprogramming after OPV vaccination as explanation for some of its epidemiological effects. Measles vaccine (MV) has shown a general but transient suppressive effect on both the lymphoproliferative and innate response evaluated in PBMCs from children [67–69]. One immunological study in infants nested within a RCT found higher plasma levels of MCP-1 and IL-1 receptor agonist(ra) after MV in females, whereas in males the effect was only moderately positive for MCP-1.
Epidemiological observations have shown that vaccines can influence morbidity and mortality more than can be ascribed to target-disease immunity. A growing number of immunological studies have helped identify possible biological mechanisms to explain these so-called nonspecific effects (NSE) of vaccines, including heterologous T-cell reactivity and innate immune memory or ‘trained innate immunity’, which involves epigenetic reprogramming of innate immune cells. Here, we review the epidemiological evidence for NSE as well as human, animal and in vitro immunological data that could explain these NSE, and discuss priorities for future epidemiologic and immunologic studies to further unravel the biology and optimize the benefits of current and new vaccines.
Can vaccines interact with drug metabolism?
2015, Pharmacological Research
Citation Excerpt :
A role for immune modulation in interactions with drugs was unveiled, based on several converging pieces of evidence. Vaccine immunisation elicits an immune response that mimics the response to the natural disease in order to provide protection against subsequent challenges, including the production of cytokines such as interferon-γ (INFγ) [19,20]. A major role of inflammatory cytokines as regulators of the expression of members of the cytochrome P450 family of oxidising enzymes (CYPs) was described in the liver.
Vaccines are safe and efficacious in reducing the burden of several serious infections affecting children and adults. Due to their efficacy, vaccines are often administered in patients with chronic diseases, likely to be under poly-therapy.
Because of several case reports indicating changes in drug metabolism after vaccination, the hypothesis of an interaction between vaccines and specific drugs has been put forward. These interactions are conceivably of great concern, especially in patients treated with molecules characterised by a narrow therapeutic index.
Herein, we review and systematise the available evidence on vaccine–drug interactions. The picture that emerges indicates that reduction in the activity of specific CYPs following vaccination may occur, most likely via interferon γ overproduction, and for specific drugs such as anticonvulsivant and theophylline may have significant clinical relevance. Clinical interaction between vaccines and drugs that are metabolised by cytochromes uninfluenced by INFγ levels, such as warfarin, are instead unlikely to happen. Further studies are however needed to gain a complete picture of vaccine–drug interactions and define their relevance in terms of possible negative clinical impact.

Immunological impact of an additional early measles vaccine in Gambian children: Responses to a boost at 3 years

They may be more susceptible to subclinical infections [20] though this event is unlikely to result in the further spread of measles [21]. CD8 T-cells are necessary to control measles viraemia [16] and the role and importance of cytotoxic T-cell responses, cellular proliferative responses and cytokine responses during and after measles or primary vaccination have been thoroughly described [15,22,23]. However, very little is known of these responses shortly after booster vaccination or natural exposure in immunized children.
Measles vaccine in early infancy followed by a dose at 9 months of age protects against measles and enhances child survival through non-specific effects. Little is known of immune responses in the short or long term after booster doses.
Infants were randomized to receive measles vaccine at 9 months of age (group 1) or 4 and 9 months of age (group 2). Both groups received a boost at 36 months of age. T-cell effector and memory responses using IFN-γ ELIspot and cytokine assays and antibody titres using a haemagglutination-inhibition assay were compared at various times.
Vaccination at 4 months of age elicited antibody and CD4 T-cell mediated immune responses .Two weeks after vaccination at 9 months of age group 2 had much higher antibody titres than group1 infants; cell-mediated effector responses were similar. At 36 months of age group 2 antibody titres exceeded protective levels but were 4-fold lower than group 1; effector and cytokine responses were similar. Re-vaccination resulted in similar rapid and high antibody titres in both groups (median 512); cellular immunity changed little. At 48 months of age group 2 antibody concentrations remained well above protective levels though 2-fold lower than group 1; T-cell memory was readily detectable and similar in both groups.
An additional early measles vaccine given to children at 4 months of age induced a predominant CD4 T-cell response at 9 months and rapid development of high antibody concentrations after booster doses. However, antibody decayed faster in these children than in the group given primary vaccination at 9 months of age. Cellular responses after 9 months were generally insignificantly different.
